* Redesign standings page with sortable table, 7-day change, and chart repositioned
- Move point progression chart below the standings table
- Replace separate Points/Projected/Placement columns with:
- Single stacked "actual / projected" Points column (shared PointsDisplay component)
- "7-Day Change" column showing points gained + rank change over past 7 days
- Remove Placement breakdown column
- Sort ties alphabetically by team name (rank sort only)
- All columns are sortable via new reusable useSortableData hook
- Add sevenDayPointChange to TeamStandingWithChange type and model

* Code review fixes: module-level comparators, correct type on SortableHead, handle negative point change, remove redundant spread
- Move comparators object to module level (closes over nothing, no useMemo needed)
- Use SortConfig<StandingRow> on SortableHead instead of inline duplicate type
- SevenDayChange: handle negative pointChange with correct sign and color
- Remove redundant sevenDayPointChange explicit assignment (already in ...standing spread)

* Update StandingsTable tests to match redesigned component
- Remove showPlacementBreakdown prop (no longer exists on component)
- Replace Placement Breakdown test suite with 7-Day Change column tests
- Update header assertion: "Placements" → "7-Day Change"
- Add tests for positive/negative point change display and rank change indicators
- Remove accessibility test for placement title attributes

* Fix movement indicator arrow count assertion to exclude sort header arrows
queryAllByText(/↑|↓/) was matching the active sort column's ↑ indicator.
Narrow to /[↑↓]\d/ so only movement indicators (↑1, ↓1) are counted.
