feat(dds): agent-first Party Master, account actions menu, FD-style statuses

- Party Master opens on agents (paged, from the server summary), then one
  agent's dashboard: accounts, maturity, money and collection cards, each
  with a View that filters the accounts table. The page title follows the
  view, and Back from an account returns to its agent.
- DDS account page: an actions menu with Edit, Premature Closure, and
  Maturity Payout & Close. The manual Close Account buttons are gone, since
  payout and premature closure close the account themselves.
- Statuses Active / Matured / Closed / Premature Closed are shown and
  filtered on every DDS screen through a shared dds-status helper.
- Premature closure dialog redesigned: term progress, numbered steps, and a
  payout calculation for each choice using the server's formulas.
- Agent & Slab Approval tab: slab approvals moved in beside agents, with
  toggle buttons and labels named for the action; richer slab review.
- Batch processing: calculation runs are reported as applied, and an empty
  run is reported as nothing to do.
