Persist UI settings v localStorage (no-subs, station, mode, ...)

User feedback: 'ko refrešam se ponovno vklopi kljukica da ni
podnapisov to bo problem'

Saved fields:
- no-subs (checkbox)
- auto-chorus (checkbox)
- include-prebuild (checkbox)
- mode (track/center/blur)
- quality (fast/medium/high)
- llm-provider (claude/gemini/auto)
- tv-station (FOLX SLOVENIJA / ONE DE / ...)

On page load: re-aplicira saved values
On change: shrani v localStorage
TV station: tudi posodobi aktiven tab style

Defaults ostanejo isti če nikoli niso spremenjeni.
