fix(case-page): resolve full-page review findings (bugs + RTL + resilience)

Full code review of the case-detail page (14 components) surfaced these,
all fixed here:

Logic bugs
- case-edit-dialog: form.reset ran on the 5s useCase refetch while the dialog
  was open, clobbering in-progress edits. Now resets only on open→true.
- status-changer: `selected` never synced to async/external `currentStatus`
  (stale dropdown). Reworked to track currentStatus until an explicit pick;
  resets to tracking after save.
- decision-blocks-panel: `block.content`/`word_count` accessed without null
  guards (endpoint has no response model) → potential render crash. Coerced
  with `?? ""` / `?? 0`. `STATUS_LABELS[status]` now falls back to the raw
  status instead of rendering literal "undefined".
- document-type-editor: `await mutateAsync()` in async click handlers without
  try/catch → unhandled promise rejection. Wrapped (errors still surface via
  isError).

Resilience / hygiene
- page.tsx: a transient 5xx on the background poll flipped the WHOLE page to
  the error card and discarded loaded data. Now gated on `!data`, plus a
  "נסה שוב" retry.
- cases.ts useUpdateCase: invalidated casesKeys.all, which re-invalidated the
  detail it had just optimistically patched. Scoped to the list prefix.

RTL correctness (logical properties)
- agent-status-widget `mr-auto`→`ms-auto`; agent-activity-feed `mr-auto`→
  `me-auto`, icon `ml-1/ml-2`→`me-1/me-2`, required `*` `mr-1`→`ms-1`;
  document-type-editor list `pr-4`→`ps-4`.

Minors
- drafts-panel: `<a href>`→`next/link` (operations + citation links) for SPA
  nav. agent-activity-feed: issueMap memoized; comment Textarea aria-label.
  upload-sheet: `unknown` status no longer shown as green success (neutral
  icon + "רענן לאישור"). citations.ts: case_name typed `string | null`.

Design gate: visual-touching items (RTL gap side, retry button, neutral
upload icon) were chair-authorized via the reviewed-findings approval ("fix
all"); none alter an approved page layout — they are correctness fixes.
tsc clean; eslint clean (1 pre-existing form.watch warning, untouched line).
