fix: assorted UI polish from review pass

- FilterPill: drop the inline value text from the active state. Pills
  now stay the same width whether or not a filter is set; the popover
  is the canonical place to read the value, and the title attribute
  surfaces it on hover.
- TopBar: remove the search input — search lives in the filter bar now.
- FilterBar: add a search input on the left, with the pill cluster
  centered between it and a flex-shrink-0 Clear-all on the right.
- LeftSidebar / HeapsPanel: count badges use a fixed-width slot
  (h-5 min-w-[24px], tabular-nums) so counts line up in the same
  visual column across rows. Empty rows reserve the slot.
- LeftSidebar: pull section counts (All Photos, Rated, Duplicates,
  Discarded) from a new useLibraryStatsQuery hook backed by the
  expanded /library/stats endpoint. Tags count was already wired.
- backend/library: stats endpoint returns per-section counts that
  match the filter the sidebar applies on click.
- Stats invalidation hooked into the standard photo-mutation paths.
- RightSidebar header: h-12 to match TopBar height.
- Timeline sticky date overlay: only show once the natural in-grid
  header has scrolled OUT of the viewport. Avoids the duplicate-label
  flash when both labels would be visible.

 You don't need to touch `mulita.yml` or the API to get started.
 
+### Configuration knobs
+
+Everything is environment-driven. `PHOTO_DIRS` is the only required
+value; the rest have sensible defaults documented in `.env.example`:
+
+| Variable             | Default | Notes                                              |
+|----------------------|---------|----------------------------------------------------|
+| `PHOTO_DIRS`         | —       | **Required.** Host path mounted at `/photos`.      |
+| `FRONTEND_PORT`      | `3000`  | SPA host port. Bump if `3000` is taken.            |
+| `BACKEND_PORT`       | `8001`  | Direct backend port (debug only — frontend uses internal nginx proxy). |
+| `REDIS_PORT`         | `6379`  | Redis host port (internal services don't need it). |
+| `ALLOWED_ORIGINS`    | `*`     | Comma-separated CORS origins for direct backend access. Lock down for prod, e.g. `https://photos.example.com`. |
+| `LOG_LEVEL`          | `INFO`  | Backend + worker log level. `DEBUG` for chasing scan issues. |
+| `TZ`                 | `UTC`   | Container timezone. Affects log timestamps and "added at". |
+| `CELERYD_CONCURRENCY`| `4`     | Parallel worker processes (scans, thumbs, metadata). Lower on a Pi, higher on a beefy host. |
+
+### Accessing from another machine
+
+The frontend talks to the backend through its bundled nginx, which
+proxies `/api/` to the backend on the internal compose network. That
+means requests are always **same-origin** as the page, so accessing
+Mulita from another host works without any CORS dance:
+
+```
+http://<your-server-ip>:3000
+```
+
+If you want to put it behind a reverse proxy at e.g.
+`https://photos.your.tld`, set `ALLOWED_ORIGINS` to that host so the
+backend's direct port (`BACKEND_PORT`) also accepts cross-origin
+requests if anything bypasses the proxy.
+
