feat(seekbar+ratings): 5 new seekbar styles and entity/mix rating system (PR #130)

Seekbar styles (5 new, by Psychotoxical):
- Neon Glow: transparent track, played section as multi-layer glowing neon tube
- Pulse Wave: flat line with animated gaussian sine pulse at playhead (rAF)
- Particle Trail: particles spawn at playhead and drift with glow (rAF)
- Liquid Fill: glass tube fills with liquid and animated wave surface (rAF)
- Retro Tape: two spinning reels connected by tape, shrink/grow with progress (rAF)

Ratings system (PR #130 by cucadmuh):
- Shared StarRating component with pulse/clear animations, disabled/locked states
- Entity ratings for albums and artists via OpenSubsonic probe (setEntityRatingSupport)
- Skip→1★: after N consecutive manual skips, set unrated track to 1★ (persisted per server)
- Mix rating filter: exclude low-rated songs/albums/artists from RandomMix, RandomAlbums, Hero, Home
- Batch refill in fetchRandomMixSongsUntilFull to fill list despite strict filters
- Prefetch artist/album ratings via getArtist/getAlbum for incomplete list payloads
- Settings: new Ratings section for skip threshold and per-axis mix filter stars
- i18n: all 7 languages (en, de, fr, nl, zh, nb, ru)
