Add per-project card statuses and a kanban board

Statuses
- Migration 006: card_statuses table (project-scoped) and cards.status_id, a
  nullable FK with ON DELETE SET NULL. Every new project is seeded with
  "To do" / "Doing" / "Done"; GET /api/projects/{id}/statuses lists them.
- New cards have no status -- they sit in an "inbox" until moved.

Project view
- Full-width and tabbed: "All tasks" (a flat list, sorted by name
  case-insensitively) and "Kanban" (Inbox plus one column per status).
- Drag a card within or between columns to reorder / restatus; the Inbox
  column has its own name + Add form.

Ordering
- Migration 007: `position` is now a dense 0..n-1 rank within a
  (project_id, status_id) column, not a project-wide order. New composite
  index idx_cards_project_status_position; existing rows re-ranked.
- PUT /api/projects/{id}/cards/order takes { status_id, card_ids } and sets one
  column's contents and order, re-parenting moved-in cards and re-packing their
  source column in a single transaction. PATCH status_id appends the card to the
  end of the destination column.

58 phpunit tests pass; the frontend type-checks and builds.
