Subject: [PATCH] feat(i18n): translate the remaining base.html modals (stage
 7b)

Manage Channels, region scope picker, Share Channel, Device Info,
analyzer registry (edit + chooser), Observer MQTT broker editor,
coordinate picker, quote dialog, map, update, backup and search.

The Settings modal (base.html ~458-1147) is still untouched - stage 8.
Where the two share markup, this commit anchors on the container id
rather than the markup: the "Loading..." spinner appears six times in
base.html and only three of them are in this slice.

Also in app.js, on the same rule as 7a - the writer that replaces a
string this slice keyed: the analyzer and broker modal titles (they
swap Add/Edit on open), the map modal title, the coordinate picker
label, and the database size line under Optimize.

Three real misses came out of the browser diff, none of which the
checker could see:

- Cancel/Save in the analyzer and broker editors were never keyed. They
  only surfaced once because the diff dedupes by text, so a single
  report line stood for both modals.
- The database size under Optimize is written by JS on open, so the
  translated server-rendered value was replaced a moment later.
- All three Device Info tabs render their bodies from app.js. Excluded
  from the check and left whole for stage 9 rather than translating the
  Share tab alone.

Left English on purpose: FTS5 query examples (hello OR world, hell*) -
the syntax is typed verbatim in any language, only what each one means
is translated - plus mqtt.example.com and the {packetHash} token.

Catalog: 573 -> 651 keys, pl at 100%. Verified with a new
i18n-stage7b-modals.js that opens each modal through the Bootstrap API
instead of its real trigger, since several are only reachable from a row
or message that may not exist on a given device.

 ### Features
 
-- **The interface can be translated, and Polish has started.** mc-webui was written English-only, with every label and message baked into the code. There is now a translation system behind it, and a **Language** setting at the top of Settings → Appearance. So far it covers the groundwork plus the panels that open in their own window — **System Log**, **Console**, **My Repeaters**, **Path Analyzer**, **Contacts** and **Direct Messages**. The main chat window and the Settings dialog follow next, so for now parts of the interface are still English whichever language you pick. Your choice applies to the browser you set it in and also becomes the default for anyone else opening the server without a preference of their own.
+- **The interface can be translated, and Polish has started.** mc-webui was written English-only, with every label and message baked into the code. There is now a translation system behind it, and a **Language** setting at the top of Settings → Appearance. So far it covers the main window — menu, chat, and its dialogs — plus every panel that opens in its own window: **System Log**, **Console**, **My Repeaters**, **Path Analyzer**, **Contacts** and **Direct Messages**. The **Settings** dialog and many of the short messages the app shows while it works are still English; they follow next. Your choice applies to the browser you set it in and also becomes the default for anyone else opening the server without a preference of their own.
 - **You can add a language yourself, without waiting for a release.** A language is a single file. Copy `en.json` from `app/translations/`, translate the values, and drop it into a `translations` folder inside your config directory — the same place the database lives. Refresh the page and it appears in the Language list, named however you named it, with no rebuild and no restart. Anything you leave untranslated falls back to English, so a half-finished translation is perfectly usable. A file you drop in also overrides one that ships with the app, so you can correct the built-in Polish on your own server. English and Polish ship in the box; everything else is open to whoever wants to write it. See [translations.md](translations.md), which explains the format and — importantly — which words to leave alone: mesh terms like flood, hop, advert, RSSI and the repeater roles stay English in every language, because that is what the firmware, the CLI and the forums all use. The Console and the log lines themselves stay English for the same reason.
 - **Times and dates behave the same in every language.** Only the words are translated — "Yesterday" becomes "Wczoraj", "5 min ago" becomes "5 min temu". The clock and the number formatting keep following your browser's own settings, so switching the menus to English will not suddenly turn your 24-hour clock into "9:53 AM". One display of large numbers on the repeater statistics page had been hard-coded to American thousands separators; it now follows your locale like everything else.
