The "Indexed X of Y pages" counter stayed stuck at "478 of 478" during a
manual "Reindex now" run instead of resetting to 0 and climbing. The status
reports indexedPages = countIndexedPages (DISTINCT pages with >=1 embedding
row), but reindex hard-replaces each page in its OWN small transaction, so
nearly all pages always have rows -> the count never drops.
Add a per-workspace live reindex-progress record in Redis (reusing the
existing global ioredis client via RedisService, no new Redis config):
- EmbeddingReindexProgressService: start/increment/clear/get over a Redis hash
with a 1h TTL self-clean; all best-effort/cosmetic so a Redis failure degrades
to the existing DB-count behavior.
- AiSettingsService.reindex seeds {total, done:0, startedAt} at enqueue time so
the very first poll already reports done=0.
- EmbeddingIndexerService.reindexWorkspace overwrites total with the real page
count at start, increments done per processed page (success or handled
failure), and clears the record in a finally (covers success, fatal abort,
and the unconfigured early-return) so a failed run never sticks.
- AiSettingsService.getMasked returns the live run numbers when a progress
record is active (plus an optional reindexing flag), else falls back to
countIndexedPages/countEmbeddablePages.
Per-page edits (reindexPage) never touch the workspace progress record, and no
mass up-front delete is introduced (search availability preserved).
Tests: indexer sets/increments/clears progress (incl. fatal abort and
unconfigured early-return); status reports run progress when active and falls
back when not.
