What 505 real channels showed that 20 demo ones could not

The favourite count sat at zero while the backend already had two: the rail
read the favourites off the StateFlow inside the composable instead of
collecting it, so it never recomposed — a regression from making favourites
work for both source types. The list collects again.

Real EPG titles broke the fixture shortener in both directions. "BL: VfB
Stuttgart - Saison 25-26" became a fixture against a season, and
"… FC Bayern München - VfB Stuttgart - 1. Halbzeit" grew a third team; a
season, a matchday, a half or a year is now rejected, and a second dash ends
the away side. The kick-off chip also gave way in the row: the line below
already carries the time, and "Bayer Leverkusen - VfB Stuttgart" needed the
width to fit at all.

Merged provider EPGs list the same programme several times, minutes apart —
the day plan showed The Big Bang Theory three times and two entries marked
as running at once. XmltvParser.collapseDuplicates folds a repeat into the
entry whose slot it falls inside.

The login code expired before anyone could confirm it: Authentik hands out a
minute, and the TV dropped back to step one without a word. It fetches a
fresh code instead, up to eight times.

Tested against the household's own Dispatcharr through api.tv.beckm4nn.net.
