feat: adds new season tag

[seferturan]

⚠️ Drafted ⚠️

Drafted to deal with the 'premier' clash

🎶 Notes 🎶

• Adds a New Season tag to calendar and releases lists, and their drilled-down pages
• Cause: both queries use group=day, so the server collapses a multi-episode day into a single entry with episode_type: multiple_episodes (or full_season). The real types only live on the nested episode.episodes[], so the premiere signal got dropped and nothing rendered
• getEpisodeStatus now resolves the premiere from the coalesced children, gated on the computed types so it doesn't reach into episodes for ungrouped entries
• Fires for a single episode, several episodes on the same day, or a full season drop
• Shows regardless of air date, so upcoming entries get it too. The plain New tag stays past-only
• Can't clash with New: single status value, and new-season takes precedence
• ⚠️ getEpisodeStatus is shared, so up-next cards now read New Season where they read Premiere before. Feels more accurate and keeps one source of truth, but shout if you'd rather I gate it to the calendar variants
  • mid_season_premiere still reads Premiere
• series_premiere shares the same tag for now. Happy to split it into its own status if we want Series Premiere back, not set in stone
