UX-08 phase 2b: short, plain status rows and page banners

Every Commissioning row and every page banner is now worded in
app/messages.py (row_*, banner_*): one sentence of at most 15 words, a red
row up to three sentences so a latch still says how it clears, banners at
most 12 words. No row names a Home Assistant entity: sensors by their
setting, solar sources by their place in the list. Reason codes and limits
stay on the log line and event list; rows keep the numbers a reader acts on.

UX-07 item 1: ClampWatchdog counts over-rating and integrator-bound
engagements separately, and after an episode each count shows under its own
alarm's title instead of both under "output clamp".

No row colour, visibility or banner order changed. Rows carry an "id" so the
tests pin meaning rather than wording. The row and banner kinds leave the
allowlist (200 -> 168, cap equal). DOCS.md gains "Status page"; choices are in
DECISIONS/UX-08-short-notifications.md.

 5. **SAFETY-32 at a roster of one.** The body no longer ends in a separate "WHICH PACK" paragraph. The pack's name is part of the first sentence ("The battery of inverter-b …"), and at a roster of one that is the only difference.
 6. **Dropped as background, now in DOCS:** "charging stays blocked" (peak reserve), "why no other guard fired" (circulating power, not delivering), and the saturation-freeze distinction (over-rating). "The meter cannot see this" stays in the circulating-power card, as the owner asked.
 7. **The Details link** opens the add-on's documentation page (`/hassio/addon/<slug>/documentation`, with the slug taken from the container hostname) and names the section. A `#heading` anchor was not used because nobody has checked that Home Assistant's documentation tab renders heading ids; if it does, adding one is a one-line change. Outside an add-on container it names the section without a link.

+# Phase 2b: status rows and page banners
+
+Every row of the Commissioning list and every banner is now in `app/messages.py` (`row_*`, `banner_*`), and `test_messages.py` checks a rendering of each. The row and banner kinds are gone from `ux08_allowlist.txt` (200 → 168 entries). DOCS.md "Status page" explains the rows. **Unchanged:** every row's colour (ok / warn / bad), which rows show when, and the banner cascade order.
+
+## Where a choice was made
+1. **A red row may use 3 sentences (30 words).** STYLE.md gave rows 15 words; the owner allows red safety states 3 sentences. A red row needs room for what happened, the state (0 W) and how it clears. STYLE.md now says so, and the test applies it by colour.
+2. **Figures left the rows, not the product.** The reason texts (freeze, sign, circulating, delivery, peak guard) carry reason codes and limits; they stay on the ERROR/WARNING log line and the event list, as before. Rows keep the numbers a reader acts on: the stall age and the 0 W deadline, the meter age and limit, asked and sent for an over-rating, the peak limit, and "opposite for 12 of 60 seconds" while a check counts. So 2a item 2 ("also on the status row") no longer holds, and DOCS.md says "in the add-on log".
+3. **No entity id on any row**, even the green ones that used to print `sensor.x = 54`. The sensor rows name the setting (*Battery power for inverter-b*). Solar sources are numbered in the order of the settings list (*source 2 of 3*, *entry 1 of the reversed-sign list*). This retires TEL-12's rule that a one-entity site reads 0.11.0's sentence byte for byte. A `tools/tel11_pv_trace.py --compare` against a pre-UX-08 tree therefore shows the PV rows as changed telemetry, and the control documents stay equal. The per-source watts and units left the multi-source row. The total, the count and which source is missing remain.
+4. **UX-07 item 1.** `ClampWatchdog` now also counts `over_rating` and `bound` separately. After an episode, each count shows under its own alarm's title ("Power request too high: 2 times since start, not now", "Battery is not keeping up: …"). A site with both gets two amber rows where it had one.
+5. **The "Not ready" banner** is the first red row's own `banner`, or else its first sentence. The peak-reserve and over-rating rows set `banner` to their notification title. The three trips keep their own banner branches, reworded (e.g. "Inverters worked against each other. Every inverter is set to 0 W.").
+6. **How a latch clears stays on the row**, shortened: "Only starting control clears this", "A restart does not clear this", "only stopping and starting control clears this" (not delivering). SAFETY-25's sentence stays on the peak-reserve row.
+7. **Rows got an `id`** (`meter_frozen`, `direction`, `pv`, …), so tests find a row by what it is, not by its words. The page ignores it.
+8. **Left for later:** texts that rows embed from other modules and that were not flagged as rows (the month-peak line, `peakguard.explain()`, the liveness and stale notes, `shadow.banner()`). The month-peak row only lost its semicolons.
