feat(reroll): add reroll button to pick another random film

[Nacchofer31]

Summary

Adds a reroll button below the film poster that lets users pick a different random movie from the cached result set without re-fetching.

Changes

• UI: New RerollButton composable (pill shape, green accent, shuffle icon) matching the pen design
• Action: OnRerollClicked wired through RandomFilmAction
• ViewModel: Caches Set<Film> from getRandomMovies, picks a random film on reroll via extractResultMovie
• Repository: getRandomMovie → getRandomMovies returning Set<Film>, new extractResultMovie method
• i18n: reroll string added across 13 locales (en, es, gl, ca, pt, fr, de, it, ru, ar, hi, zh, ja)
• Design: Migrated icon_font → icon format and updated stroke definitions in randomboxd.pen

Commits

• feat(reroll): add reroll button UI with i18n
• feat(reroll): add reroll logic in ViewModel
• style(design): migrate icon format in pen file
