Add a channelLanguageDetection service that scores language evidence
per IPTV variant (country/language prefixes in name and group, source
metadata, original title words) and picks the highest-scored language.
Integrate detected languages into channel variant grouping and add a
language selector to the live player to switch to a variant of the
logical channel in the desired language, keeping raw streams
non-destructive.

Add a channelVariantGrouping service that normalizes channel names
(strips region prefixes and quality tokens) to fingerprint duplicate
stream entries and cluster them under a single logical channel with
quality/source variants. Wire it into the Live TV channel list and
player variant selection, reducing duplicates without destructively
merging streams.

Manual quality profiles (source/1080p/720p/480p) in the player overflow
menu plus an honest/preparatory Auto contract: adaptive when the HLS
manifest exposes multiple levels, single-rendition automatic selection
otherwise.
- server: transcodeQualityProfiles service and qualityMode session option
- player: quality menu, persisted preference, live switch with rollback
- tests: npm test script and unit tests for quality profiles
