radio: session log update — index UI exposes classifier filters

Backend min_score/exclude_banter wired through to HTML index. Adds
score badges (1-5 red->green), topic_class pills, dim styling on
banter rows. Live on http://172.16.3.20:8765/. Synced to portable
repo. pscp ENOSPC quirk worked around by plink-stdin streaming.

+## Update: 06:05 — Index UI exposes classifier filters
+
+User asked to wire the new classifier fields into the search UI. The
+backend already supported `min_score` and `exclude_banter` query params
+(commit `5e3b1a2`); this update brings them into the HTML index and adds
+visible quality indicators on Q/A hits.
+
+### Update Summary
+
+Edited `INDEX_HTML` in `server/main.py` to add two filter controls and
+score badges. Verified locally via `uvicorn` on `127.0.0.1:8866` against
+the classifier-populated DB (no-filter, `min_score=4`, and
+`exclude_banter=true` modes all behaved correctly). Hit an unexpected
+`No space left on device` from `pscp` despite Jupiter having 37 TB free
+on `/mnt/user`; bypassed by streaming the file through plink stdin
+(`plink ... "cat > /path" < local_file`). md5 verified byte-identical.
+Container rebuilt via `docker compose up -d --build`. Synced the same
+`main.py` to the portable repo so the laptop UI stays in sync.
+
+### What changed in the UI
+
+- **`min score` select** — values: any, 2+, 3+, 4+, 5. Default `any` to
+  preserve old search behavior. Filters surface 1,096 mid-and-above
+  pairs at `3+` or 523 useful pairs at `4+`.
+- **`hide banter` checkbox** — when checked, drops the 606 rows with
+  `is_banter=1`.
+- **Score badge per Q/A hit** — small color-coded number (1=red, 5=green)
+  next to each hit's metadata line. Title attribute shows
+  `usefulness N/5` on hover.
+- **Topic class tag** — small gray pill showing `computer-help`,
+  `banter`, `off-topic`, `promo`, or `unclear`.
+- **Dimmed rendering** — hits with score 1-2 or `is_banter=true` render
+  at 55% opacity. Visible but visually de-emphasized so good hits stand
+  out at a glance.
+- **`escapeHtml` helper** — defensive XSS guard on `caller_name` and
+  `title` (transcript-derived strings).
+
+### Key Decisions (this update)
+
+- **Default filter "any"** — preserves prior search habits and saved
+  URLs. Mike opts into filtering when needed rather than being forced
+  into a curated view.
+- **`URLSearchParams` instead of string concat** — only emits
+  `min_score=` / `exclude_banter=` when non-default, keeping URL bar
+  clean for the common case.
+- **Color-coded badge with both score AND topic tag** — score is
+  numeric/comparable; topic tag is categorical and explains *why* a
+  score is what it is. Both together make the classifier's reasoning
+  visible at a glance without forcing a click.
+- **Dim instead of hide for low-quality hits** — keeps everything
+  visible by default; the filter controls are the explicit "hide" lever.
+- **Used `plink "cat > path"` instead of pscp** for the deploy when
+  pscp failed — faster than diagnosing the underlying scp/shfs issue
+  and gets the job done deterministically.
+
+### Problems Encountered (this update)
+
+- **pscp ENOSPC despite 37 TB free** — `pscp main.py` failed with
+  `No space left on device` on two retries. df showed 37 TB free on
+  `/mnt/user`, df -i showed inodes fine. Workaround:
+  `plink ... "cat > /path/main.py" < local_main.py`. md5sum confirmed
+  byte-identical post-transfer. Likely Unraid shfs cache-pool churn or
+  an issue with overwriting an in-use file from inside a container's
+  mount. Worth understanding eventually but didn't block the deploy.
+- **plink output buffering on chained docker commands** — long
+  `docker compose up -d --build` runs hung from Bash's run_in_background
+  view (output file stayed empty for minutes). Foreground sync run with
+  the same command worked instantly. Same pattern observed yesterday.
+  Workaround: don't background long plink runs; just block.

+### Status at update end
+
+- UI controls live on http://172.16.3.20:8765/ and on the portable repo
+- Backend filters working (verified end-to-end)
+- Untouched: HTML still has no per-hit deep-link to `/api/episodes/{id}`
+  (clicking a hit doesn't navigate). Future enhancement.
+- Pending: laptop validation (still next week's task)
