chore: reset NIGHTLY_CHANGELOG.md after nightly-0.9.28-nightly48 release

The printer's file/fileDetails MQTT action extracts and base64-encodes
the embedded "; thumbnail begin" block from a GCode file's header on
demand and returns it inline as data.file_details.thumbnail - verified
live against a real Kobra X (a valid 230x110 PNG came back for an
existing print file).

New endpoint GET /kx/printer-files/{filename}/thumbnail wraps this via
the existing _wait_for_file_action() helper (same fire-and-forget +
file/report-callback pattern as listLocal/deleteBatch). Results are
cached in-memory per filename (self._printer_thumbnail_cache) - a
file's thumbnail never changes while it exists on the printer, and the
tab can list 100+ files at once.

Frontend fetches thumbnails lazily through a small sequential queue
(_printerThumbQueue/_pumpPrinterThumbQueue) after rendering the file
list, one request at a time rather than firing 100+ concurrent MQTT
roundtrips, and swaps each card's placeholder printer icon for the
real <img> once its thumbnail arrives. Client-side cache
(_printerThumbCache) avoids re-fetching on re-render (e.g. after a
selection change).

Verified end-to-end against the real printer and visually via
Playwright: all 10 listed files rendered their actual, distinct print
preview thumbnails instead of the generic icon.

 ## Changes in this build
 
-- Fix: on printers with multiple daisy-chained ACE units and no toolhead buffer (e.g. Kobra S1 with 2 ACE Pro), only the first unit's 4 slots were ever shown on the dashboard or synced to OrcaSlicer — the bridge silently discarded every ACE unit after the first. All units now show up correctly (Issue #95, thanks @hoovercl for the detailed report and logs)
-- Feat: the GCode browser now supports multi-select and bulk delete — click any file's checkbox to enter select mode, use "Select All" to grab everything currently visible (respecting your active search/filter), then delete the selection with one confirmation instead of one-by-one (Issue #94, thanks @Blaim)
-- Fix: **printing via OrcaSlicer "Upload and print" failed (or fed the wrong spool) when a slot below the used filament was empty** — e.g. printing with Filament 4 while slot 3 was empty. The generated AMS slot mapping inserted a placeholder pointing at the physically empty tray, which the printer rejects. Placeholders now point at a loaded tray instead. Printing with all slots full already worked and is unchanged.
-- Fix: manually assigning a filament profile to an ACE slot could crash the MQTT callback (`'list' object has no attribute 'get'`) when the printer rejected the assignment, e.g. for custom-RFID/third-party filament. The bridge now handles the printer's failure response cleanly instead of crashing, and the log now correlates a rejected assignment with the request that triggered it (slot/type/color) so a rejection reason can be diagnosed from bridge logs alone (Issue #100, thanks @Blaim)
-- Fix: **the camera stream could hang forever after a printer reboot** — the printer rotates its stream token on reboot, but the running ffmpeg processes kept reading from the stale, now-silent connection and never noticed. The bridge now detects the URL change and automatically restarts the camera pipeline, ffmpeg itself now times out on a stalled read as a second line of defense, and `/api/camera/stream` now returns a proper 503 instead of hanging if no frame arrives within 5s (Issue #99, thanks @fmontagna for the excellent root-cause analysis and reproduction)
-- Fix: shrinking the Progress dashboard tile below its default height clipped the lower content (time grid, filename, buttons) out of view instead of scaling with it; dashboard tiles in general could show a scrollbar even when there was nothing to scroll. Both fixed (Issue #97, thanks @Blaim)
-- Feat: custom ACE-RFID filament tags (e.g. written via the "ACE RFID" app for third-party spools) are now matched automatically against your imported OrcaSlicer profiles. Anycubic's ACE RFID system concatenates vendor + material + a truncated serial into one type string (e.g. "GEEETECH PLA Bas") for custom tags — the bridge now recognizes the vendor prefix and resolves it to your already-imported profile instead of falling back to a generic default, so no manual per-slot reassignment is needed anymore (Issue #101, thanks @Blaim)
-- Fix: `server/files/metadata` could leak the currently/last tracked print job's layer count and estimated time into a query for a *different* file, since those values were read from live state before falling back to the queried file's own stored metadata. Now only the currently-tracked file's own query uses live state — any other filename relies solely on its own record (Issue #102, thanks @fmontagna)
-- Fix: `curr_layer`/`total_layers` (and, after a successful print, every other per-job field — progress, filename, duration, etc.) were never reset when a print finished normally, only on stop/cancel — they stayed at the last job's values until the next print happened to overwrite them (Issue #102, thanks @fmontagna)
-- Fix: the printer's own progress value during pre-print phases (auto-leveling/preheating/bed-checking) was passed straight through to `virtual_sdcard.progress`/`display_status.progress`, causing it to jump non-monotonically once real printing started and progress reset. Pre-print progress is no longer forwarded (Issue #102, thanks @fmontagna)
