[pull] master from mattermost:master - #870

* add testcontainers to playwright-lib

* include retry mechanism for transient failures

* - Introduced a new command `testcontainers:up` in package.json to run Playwright tests with Testcontainers.
- Created a standalone Playwright configuration file `playwright.testcontainers-up.config.ts` for managing Testcontainers.
- Added a no-op test `testcontainers_up.spec.ts` to ensure the Testcontainers stack is up during the test run.
- Implemented a global setup script `testcontainers_up_global_setup.ts` to start and stop the Testcontainers stack.
- Updated dependencies in package.json, including adding `chalk` for logging.

* fix package-lock

* fix tsc and restore waiting for all migrations to complete

The mobile navbar slide-out (.navbar-sidebar) always has a dark denim
background regardless of theme, but its menu links inherited the
light-mode --ifm-menu-color* values tuned for the light desktop
sidebar, rendering dark navy text on a dark navy panel. Scope the
dark-on-dark ("readable on dark") menu color values to .navbar-sidebar
unconditionally, and fix the "Back to main menu" button's text color
which was relying on the same now-changed background.

* docs(sidebar): regroup Administration Guide Onboard and Scale sections

Onboard (34 files) and Scale (28 files) were still flat, unrouped lists
unlike their already-regrouped Configure/Manage/Integrations siblings.
Apply the same manual-grouping-override pattern:

- Onboard: SAML SSO, Other SSO & Identity (OAuth/OIDC/AD-LDAP),
  Multi-Factor & Certificate Auth, Guest Accounts & Delegated
  Administration, User Provisioning & Bulk Data, Migrating to Mattermost.
- Scale: Capacity Planning (scale-to-N-users pages + storage sizing),
  High Availability & Architecture, Search Infrastructure, Observability
  & Monitoring, Caching — with Scaling for Enterprise kept as a standalone
  landing page since it's a general entry point, not a group member.

Extends the existing orphan-check warning logic in buildAdminGuideSidebar
to also cover Onboard/Scale, so future filesystem drift surfaces the same
way it already does for Configure/Manage. Files stay flat on disk, no
URLs move.

* docs(sidebar): align Onboard/Scale subgroups with Sphinx's live nav

Sphinx's actual toctree groups these files differently than the initial
regroup guessed: SAML/OAuth/OIDC/AD-LDAP all live under one identity
bucket (not split SAML vs "other"), guest/permissions pages sit under a
plain "User management" label, and — most notably — 21 of Scale's 28
files (capacity planning, HA/architecture, search infra, caching) are
navigated to from Deployment Guide -> Reference Architecture in Sphinx,
not Administration Guide, even though their Sphinx URLs stay under
/administration-guide/scale/.

- Merge Onboard's samlSso/otherSso groups into one "SSO & Identity"
  group, with SAML nested as its own sub-category inside it.
- Rename "Guest Accounts & Delegated Administration" to "User
  Management".
- Physically move the 21 Scale files that Sphinx navigates to from
  Deployment Guide into deployment-guide/reference-architecture/scale/,
  and add a new `scaling` group to DEPLOYMENT_GROUPS mirroring that
  split. Administration Guide -> Scale keeps only the 7
  monitoring/observability pages.
- Rewrite the ~130 internal .mdx links that pointed at the old
  /administration-guide/scale/* paths for the moved files, and update
  the 31 matching Sphinx->Docusaurus redirect targets in
  active-redirects.json.

Regenerated the sidebar with zero orphan warnings; all files accounted
for exactly once.

* docs(sidebar): flatten Scale's remaining Observability & Monitoring group

With the 21 architecture/capacity/search files moved to Deployment Guide,
Scale is down to 7 monitoring pages under one theme — wrapping them in
their own "Observability & Monitoring" sub-category just adds a redundant
nesting level (Scale > Observability & Monitoring > 7 files). List them
flat directly under Scale instead.

* docs(sidebar): move Calls docs to deployment-guide, dissolve Storage & Database group

Calls (RTCD, offloader, Kubernetes, logging, metrics) is a deployment/
operations concern, not settings-reference material — physically move the
6 Calls docs from administration-guide/configure/ into a new
deployment-guide/calls/ directory and add a matching `calls` group to
DEPLOYMENT_GROUPS, slotted right after Server/Scaling. Rewrite every
cross-reference across docs/ (including the two PDF book manifests) to the
new /deployment-guide/calls/calls-* paths, and add/update the matching
active-redirects.json entries so old URLs keep resolving.

Also dissolve the "Storage & Database" group in Configure — its three
pages (configuration-in-your-database, environment-variables,
azure-blob-storage) become plain top-level entries instead of a
single-purpose subgroup; no files move since their URLs are unchanged.

* docs(calls,scale): fix RST-migration artifacts and stale links flagged in review

Fixes still-valid review findings on the Calls/Scale content moved in this
branch:

- calls-metrics-monitoring.mdx: unescape HTML-entity braces in inline RTCD
  metric names (&#123;/&#125; -> {}), which is unnecessary in fenced/inline
  code and rendered literally; convert two legacy docs.mattermost.com
  absolute links to root-relative internal links, pointing the
  Prometheus/Grafana link at its current post-move location under
  deployment-guide/reference-architecture/scale/ rather than the stale
  administration-guide/scale/ path.
- calls-rtcd-setup.mdx: convert the ICE Host Override link to a
  root-relative path; convert two leftover Sphinx ```{note}``` fences to
  the <Note> component (one of these was rendering as barely-readable
  plain text due to being an unrecognized code-fence language, not a
  proper admonition); add a <Warning> ahead of the community-maintained
  installation scripts link.
- elasticsearch-setup.mdx: remove a stray leftover ":start-after:
  :nosearch:" Sphinx directive rendering as literal page text.
- opensearch-setup.mdx: remove blockquote (`>`) prefixes wrapping every
  numbered-step code fence (another RST-migration artifact), convert a
  raw <div class="note"> to <Note>, and unescape HTML-entity braces/angle
  brackets in the YAML/JSON/Terraform examples.
- deploy-rhel.mdx: fix the "RTCD setup and configuration" link to point
  at calls-rtcd-setup instead of the general calls-deployment-guide page.
- pdf/books/deployment-guide.json: add the two Calls pages missing from
  the PDF spine (calls-metrics-monitoring, calls-rtcd-setup).

Skipped: the raw entity-escaped `{}` in calls-rtcd-setup.mdx's <style>
block is intentional (real JSX context, not a code fence/span) and the
"code comment colors nearly invisible" screenshot turned out to be the
same {note}-fence bug above, not a separate Prism/CSS issue -- fixed by
the <Note> conversion. Two more Sphinx ```{note}``` fences exist in
administration-guide/onboard/sso-saml-keycloak.mdx and
sso-saml-adfs-msws2016.mdx but weren't part of the flagged findings, so
left untouched.
