Refactor timerWakeCycle() to fetch a single random photo per wake
using cycle-mode-aware server-side filtering via Immich's
POST /api/search/random endpoint.
Changes:
- Add fetchOneRandomAssetId() to ImmichClient with support for
isFavorite, takenAfter, takenBefore filter parameters
- Add timer_last_date NVS field for chronological cursor persistence
- Implement probabilistic filter selection per cycle mode:
- Random: unfiltered size=1
- Chronological/ReverseChronological: date cursor in NVS
- FavoritesWeighted: 66% favorites, 33% unfiltered
- WeightedChronological: 66% recent (30d), 33% unfiltered
- WeightedReverseChronological: 66% older (30d), 33% unfiltered
- Add retry loop with filter relaxation on empty results
- Initialize hardware RTC (RX8130CE) firmware-wide:
- Seed system clock from RTC at boot (immediate time)
- NTP sync after WiFi connect, write back to RTC
- Add time_utils.h with isoNow(), isoNowMinus30d(), hasValidTime()
Normal mode (PhotoQueue + displayTask) is completely untouched.

Album selection now controls which photos are displayed.
Uses POST /api/search/random with albumIds filter (Immich v3
compatible) instead of the removed GET /api/albums/{id} assets.
- Add albumIds parameter to fetchRandomAssets/fetchRandomAssetIds
- syncFromAlbums: fetch random assets filtered by selected albums
- syncFromAllPhotos: preserve existing global random behavior
- Album mode reshuffles on exhaustion instead of re-fetching
- 24h resync checks album assetCounts for changes before re-fetch
- requestSync + albums_changed action triggers queue rebuild on save
- timerWakeCycle respects album selection
- Discard stale pre-renders on album change

Root cause: Panel_ED2208's epd_quality mode applies _dither_row_rgb_pair
(diagonal bias pattern with dither=140) during _exec_transfer(). Since our
ImagePipeline already does proper Floyd-Steinberg dithering, the driver's
additional dithering was creating visible diagonal artifacts.
Fix: setEpdMode(epd_fastest) selects _dither_row_none (clean nearest-color
lookup, no spatial bias). On Panel_ED2208 this only affects the dither
function — NOT refresh quality or waveform.
Also: default dither_noise setting to OFF since error scatter was targeting
the wrong layer (it made gradient areas fuzzier without fixing the real
problem in the display driver).

- Replace center-crop with fit-contain (no photo cropping)
- Letterbox bars filled with adjacent edge average color
- Queue fetches in batches until 50 usable assets
- Auto-refill queue on exhaustion, dedup via shown history
- Filter RAW files from asset selection
