feat: improve league home standings and sports seasons UX (#65)
- Sort sports seasons by status (active → upcoming → completed), with
  season_standings pattern last within active, then alphabetical
- Fix rank display for teams without standings: T1 when no scores exist,
  T{n+1} when some teams are scored (avoids misleading T1 for unranked teams)
- Extract rank logic to getDisplayRank() in standings-display.ts with tests
- Pre-compute standingsMap and sortedTeams to eliminate O(n²) render lookups
- Fix invite URL SSR flash by deriving origin in the loader
- Guard toast useEffect with processedParamsRef to prevent double-fire
- Hide Teams Filled and Draft Order Set post-draft; show Standings sidebar
  link only when active/completed
- Show "Final standings" label when season is completed
- Remove duplicate Season Status from sidebar; add Flex Spots description
- Fix status type cast to occur at the model mapping layer, not in JSX
