Add enforceValueInOptions prop to Select

[lbwexler]

Adds an opt-in enforceValueInOptions prop to the desktop and mobile Select components, addressing #4111.

When enabled, the control keeps its value constrained to the current options: whenever either the value or the options list changes, any selected value not found in options is automatically removed — cleared to emptyValue for single selects, or filtered out of the array for multi (desktop). This replaces the app-level reactions teams write today to reconcile a selection against reloaded options.

Notes

• Enforces on both triggers (options reload and a value set/bind) via a reaction tracking both, so the invariant holds regardless of which side changed. Idempotent, so no reaction loop.
• Throws if combined with enableCreate or queryFn, where values may legitimately fall outside options.
• Because it fires immediately, a value set before options load will be removed — documented on the prop; not for use alongside late-loading options / generateOptionFn.

Closes #4111
