fix(firmware): parse P2S/X2D wiki anchors without dash and full-width parens (#1030)

  The wiki scraper silently returned no versions for P2S and X2D, causing
  Bambuddy to fall back to the Bambu Lab download page, which still listed
  01.01.01.00 as "latest" even though 01.02.00.00 shipped on 2026-04-09.

  Two regex mismatches in _fetch_all_versions_from_wiki():

  1. Heading anchor ids require an optional dash between version bytes and
     date. H2D/X1/H2C/H2S use "h-01020000-20260409"; P2S and X2D publish
     "h-0102000020260409" (no dash).
  2. The text fallback only matched ASCII parens around release dates, but
     P2S, X2D, A1 and A1-mini render dates in full-width parens （YYYYMMDD）
     (U+FF08/U+FF09).

  Anchor regex now accepts an optional dash; fallback accepts both paren
  styles. Added regression tests for both shapes.

 ### Fixed
+- **P2S Firmware Check Shows Stale "Latest" Version** ([#1030](https://github.com/maziggy/bambuddy/issues/1030)) — On P2S (and X2D) the Firmware Info modal reported `01.01.01.00` as the newest available release even though `01.02.00.00` had shipped on the Bambu Lab wiki weeks earlier, so the "update available" badge never appeared. Two silent regex mismatches in the wiki scraper caused `_fetch_all_versions_from_wiki()` to return an empty list: (1) the section-heading anchor parser required a dash between the version bytes and the release date (`id="h-01020000-20260409"`), but P2S and X2D publish anchors without the dash (`id="h-0102000020260409"`); (2) the text-based fallback only accepted ASCII parens around the date, while P2S, X2D, A1 and A1-mini headings render dates in full-width `（YYYYMMDD）` (U+FF08/U+FF09). When both paths failed, the code silently fell back to the Bambu Lab download page, which still lagged at `01.01.01.00`. The anchor regex now accepts an optional dash and the fallback accepts both paren styles; added regression tests for the no-dash anchor and full-width paren shapes. Thanks to @Minebuddy for reporting.
 - **Library File Print-Usage Tracking** ([#1008](https://github.com/maziggy/bambuddy/issues/1008)) — `LibraryFile.print_count` and `last_printed_at` are now updated on every successful queued print completion. Previously both fields were defined on the model and displayed in the File Manager, but nothing ever wrote to them — every file in every library showed as never printed. Now counts increment cumulatively and `last_printed_at` stamps the completion timestamp (UTC). Failed, cancelled and user-aborted prints are intentionally excluded, so the fields represent "successful usage" rather than "attempted usage." This unblocks sorting the File Manager by last-printed date and is a prerequisite for the scheduled-purge feature requested in #1008. Thanks to @cadtoolbox for the report.
