feat: view full log line in monit dashboard

[ButchAnton]

Problem

The Logs panel in pm2 monit / pm2 dashboard (lib/API/Dashboard.js)
renders each entry as one row in a blessed.list. Anything wider than the
panel is silently clipped, with no way to see the rest — no wrapping, no
horizontal scroll, no detail view. Long lines (stack traces, JSON payloads,
long URLs, etc.) are simply unreadable in the dashboard today.

What this adds

Pressing Enter on a selected line in the Logs panel opens a scrollable
overlay with:

• The full, wrapped, untruncated text of that line
• Process name
• Stream (stdout / stderr / pm2-internal)
• When the dashboard received it
• A best-effort detected timestamp and log level, parsed out of the line's
  own text (many apps prefix their own lines with these, independent of
  pm2's stream typing)

Pressing Enter again closes the overlay and returns focus to the Logs panel.
The footer hint text is updated accordingly.

Implementation notes

• A parallel rawLogLines buffer stores untruncated text + metadata per
  line, evicted in lockstep with the existing logLines (display strings)
  buffer, so memory usage is unaffected.
• The overlay listens for List's select event (emitted only from
  enterSelected, i.e. an explicit Enter), not select item (emitted on
  every navigation via List.prototype.select, including the refresh-driven
  setItems() calls) — so it only opens on Enter, never as a side effect of
  scrolling or the dashboard's periodic refresh tick.
• Log text coming through loggers like Winston can carry raw ANSI SGR codes
  around level words (e.g. "\x1b[32minfo\x1b[39m:"). Left in place, the
  escape sequence's trailing letter sits directly against the word with no
  regex word boundary between them, silently breaking level detection — so
  these are stripped before storage.

Testing

This file has no existing automated test coverage (it's a blessed
terminal UI with no headless test harness in this repo). I tested manually
via tmux (driving the real interactive dashboard with tmux send-keys /
capture-pane against live pm2-managed processes) and via a small
synthetic harness that calls Dashboard.init() / .log() /
.showLogDetail() directly to exercise ANSI-stripping and level-detection
against realistic Winston-colorized output. Verified:

• Long lines (a 2000+ char JSON line) render fully wrapped in the overlay
• Enter opens/closes the overlay correctly and returns focus to the Logs
  panel
• Up/down scroll works inside the overlay for content taller than it
• Detected timestamp/level render correctly, including with ANSI-colorized
  input
• No regressions to existing board-switching (left/right) or quit
  (Escape/q/Ctrl-C) behavior
