[AZ-497] [AZ-498] [AZ-499] Cycle 2 New Task: epic, stories, contract draft

Closes autodev existing-code Step 9 for cycle 2.

- Epic AZ-497 (Self-Hosted Satellite Tiles - SPA Integration) added
  to _docs/02_tasks/_dependencies_table.md as the cycle-2 umbrella.
- AZ-498 (5 pts): self-hosted satellite tiles + drop map-type toggle.
  Cross-workspace prereq: satellite-provider must add cookie-auth on
  GET /tiles/{z}/{x}/{y} before merge (user files separately).
- AZ-499 (2 pts): mission-planner OWM env-var hardening + closes the
  AZ-482 source-scan gap with a new owm_key_in_source banned-deps kind.
- Contract _docs/02_document/contracts/satellite-provider/tiles.md
  v1.0.0 (draft): slippy-tile XYZ shape both sides commit to.
- _docs/_autodev_state.md: Step 9 closure note + advances pointer to
  Step 10 (Implement) for cycle 2.
