The syncNTP() call blocks up to 5 seconds waiting for NTP response on
every deep sleep wake cycle (every 10 minutes). Combined with mDNS
startup, this added significant active WiFi time per cycle.
Fix: Add 'minimal' flag to WiFiManager::begin()/startStation(). In
the deep sleep wake path, skip NTP sync and mDNS entirely. The system
clock is already seeded from the hardware RTC at boot, which is
accurate enough for 30-day date window calculations.
Normal interactive boot still does full NTP sync + mDNS as before.

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

Refactor displayTask() into two phases: display and pre-render.
After showing a photo, the next one is immediately downloaded,
decoded, and dithered into a pending framebuffer (~240KB PSRAM).
When the slideshow timer fires, the EPD refresh starts instantly
without the previous 2-5s pipeline delay.
- Add PendingPhoto struct with settings hash for staleness guard
- Extract displayPhoto() and prepareNextPhoto() helpers
- Manual next/random discards pre-render and goes inline
- Falls back to inline pipeline if pre-render unavailable
- No changes to ImagePipeline, DisplayManager, or other modules

Presets are now [1, 2, 5, 10, 15, 30, 60] minutes. A 'Custom' button
reveals a number input clamped to 1–60 minutes. Backend also clamps
the received value with constrain(v, 1, 60) for safety.

Shift icons up 1px to better match the text midline, and increase
ICON_GAP from 4 to 6 for more breathing room between icon and text.

Draw pin icon on the location badge and calendar icon on the
datetime badge when displaying a single photo (not side-by-side).
Icons are rendered using M5GFX shape primitives (fillCircle,
fillTriangle, drawRect, fillRect, drawLine) - no bitmap data needed.
Icons only appear when regionW == DISPLAY_WIDTH to avoid cluttering
the narrower badges used for portrait-pair layouts.

- Location gets its own badge in the lower-left corner (separate from
the main date/time/people/camera badge at the configured position)
- All overlay badges now use rounded corners (radius 4px) via
fillRoundRect instead of fillRect
- New setting: 'Translucent background?' checkbox in web UI
When enabled, badge backgrounds use a checkerboard pattern (every
other pixel black) instead of solid black, creating a 50% opacity
effect that lets the underlying image show through
- Refactored all badge drawing through a single drawOverlayBadge()
helper (metadata, sleep indicator, battery indicator)

Replace the PALETTE_565 + writePixel loop with a bgr888_t palette whose
values exactly match Panel_ED2208's internal epd_palette, pushed via a
single pushImage() call.
Benefits:
- Eliminates ~240K individual writePixel calls per frame
- Zero-distance palette values guarantee correct color mapping
- Removes lossy RGB565 intermediate encoding
- Remove unused paletteToColor565() helper
Also adds informational comment to triggerRefresh() noting that
Panel_ED2208::_exec_transfer always sends the full 400x600 frame.

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).

- Letterbox: extend edge pixels outward with blur + fade to solid color
- Portrait: detect and pair portraits side-by-side, fallback to solo
- Metadata: add overlay mode (corner badge), time field, custom date/time
format strings (strftime), font size 1.5x, region-aware for pairs
- Buttons: swap G9/G10 to match physical layout, double-press random
button for deep sleep, SLP indicator drawn before sleep
- Boot: remove redundant 'Loading photos' screen (saves 17s refresh)

- 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
