fix(ui,i18n): E30 review round 2 — honest bio failure, a full show summary, one HU name per thing

- Person page: a bio ask that fails says so with a retry instead of reading as 'no biography'.
- Show page: the summary is a ClampedText (5 lines + More), like the person and collection pages;
  one More/Less pair (plex.textMore/textLess) for all three.
- Channels: a re-slotted row is placed in the language the server orders by (the stored
  preference, else English), not the UI's guess.
- A skipped run's body is only the reason (its title already says skipped).
- HU: Behúzási kvótatartalék; Eseménynapló ürítve / az eseménynaplót; indok; közvetlenül
  játszható / közvetlen közvetítés in the Plex hints.
- Tests: ClampedText re-measures on a resize, the show summary clamp, serverOrderLang.
