4grayandClaude Opus 4.7 d6a91d79e9 perf(bundle): dynamic-import iptv-playlist-parser to drop 130KB validator from eager bundle

iptv-playlist-parser statically imports the entire validator library
(~130KB across 113 files). Because PlaylistsService is eager (re-exported
through the 'services' barrel that AppComponent imports), validator was
landing in the cold-start preloaded chunk even though parse() only runs
on user-triggered playlist imports (FILE/URL/TEXT add).

Switch handlePlaylistParsing() to dynamic-import the parser. The two
callers (playlist-backup.service and the parsePlaylist$ NgRx effect)
needed minor adjustments — the effect now uses mergeMap(from(...)) to
flatten the Promise back into the action stream.

Cold-start preloaded chunk: 1511KB -> 1374KB (-9%).
Validator now sits in a separate ~129KB chunk that loads only when
the user adds a playlist.
