* refactor(timeline): drop server-side comment + timeline pagination (MUL-1929)

The cursor-paginated /timeline and /comments endpoints were sized for a
problem the data shape doesn't have: prod p99 is ~30 comments per issue
and the all-time max is ~1.1k. Time-based pagination also splits reply
threads across page boundaries (orphan replies), which the frontend was
papering over with an "orphan rescue" that promoted disconnected replies
to top-level — confusing UX with no real benefit.

Replace both endpoints with a single full-issue fetch, capped server-side
at 2000 rows as a defensive safety net (never hit in practice).

Server
- /api/issues/:id/timeline now returns a flat ASC TimelineEntry[]
  (matches the legacy desktop contract — older Multica.app builds keep
  working because the wrapped TimelineResponse + cursors are gone, and
  the raw array shape was always what they consumed).
- /api/issues/:id/comments drops limit/offset; only ?since is honoured
  for the CLI agent-polling flow.
- Drop ListCommentsBefore/After/Latest, ListActivitiesBefore/After/Latest
  and the timelineCursor encoding.
- Replace with ListCommentsForIssue / ListCommentsSinceForIssue /
  ListActivitiesForIssue (capped by argument).

CLI
- multica issue comment list drops --limit / --offset and the X-Total-Count
  reporting; --since is preserved for incremental polling.

Frontend
- Replace useInfiniteQuery with useQuery in useIssueTimeline; drop
  fetchOlder/Newer, jumpToLatest, isAtLatest, newEntriesBelowCount.
- Remove timeline-cache helpers (mapAllEntries / filterAllEntries /
  prependToLatestPage) and the TimelinePage / TimelinePageParam types.
- WS event handlers update the single flat-array cache directly.
- Drop the orphan-reply rescue in issue-detail — every reply's parent
  is now guaranteed to be in the same array.
- Strip the "show older / show newer / jump to latest" buttons and their
  i18n strings.

* fix(timeline): address review feedback on pagination removal

Three issues caught in PR #2322 review:

1. /timeline broke for stale clients between #2128 and this PR. They send
   ?limit/?before/?after/?around and parse with the wrapped TimelinePageSchema;
   the new flat-array response was failing schema validation and falling back
   to an empty timeline. Restore the wrapped shape on those query params
   (DESC entries, null cursors, has_more_*=false), keeping the flat ASC array
   for bare requests. Around-mode now also fills target_index from the merged
   slice so legacy clients can still scroll-to-anchor without a follow-up.

2. The agent prompts in runtime_config.go and prompt.go still told agents
   that `multica issue comment list` accepts --limit/--offset and to use
   `--limit 30` on truncated output. With those flags removed in this PR,
   new agent runs would hit "unknown flag" or skip context. Update the
   prompt copy to "returns all comments, capped at 2000; --since for
   incremental polling".

3. useCreateComment's onSuccess was a bare append to the timeline cache
   with no id-dedupe, so a fast comment:created WS event firing before
   onSuccess produced a transient duplicate. Restore the id guard the old
   prependToLatestPage helper used to provide.

Adds two new boundary tests:
- TestListTimeline_LegacyWrappedShape_OnPaginationParams
- TestListTimeline_LegacyWrappedShape_AroundFillsTargetIndex

* test(handler): fix timeline test assertions for handler-package isolation

The TestListTimeline_* assertions assumed CreateIssue would seed an
"issue_created" activity_log row, but the activity listener that publishes
those rows is registered in cmd/server/main.go — handler-package tests
don't wire it up. CI saw 5 entries (3 comments + 2 activities) where the
test expected ≥6.

Drop the auto-activity assumption: assert exactly 5 entries in
TestListTimeline_MergesCommentsAndActivities, and tighten
TestListTimeline_EmptyIssue to assert a fully-empty timeline.
