Abhimanyu Yadav e32d258a7e feat(blocks): add AgentMail integration blocks (#12417)
## Summary
- Add a full AgentMail integration with blocks for managing inboxes,
messages, threads, drafts, attachments, lists, and pods
- Includes shared provider configuration (`_config.py`) with API key
authentication
- 8 block modules covering ~25 individual blocks across all AgentMail
API surfaces

  ## Block Modules
  | Module | Blocks |
  |--------|--------|
  | `inbox.py` | Create, Get, List, Update, Delete inboxes |
| `messages.py` | Send, Get, List, Delete messages + org-wide listing |
  | `threads.py` | Get, List, Delete threads + org-wide listing |
| `drafts.py` | Create, Get, List, Update, Send, Delete drafts +
org-wide listing |
  | `attachments.py` | Download attachments |
  | `lists.py` | Create, Get, List, Update, Delete mailing lists |
  | `pods.py` | Create, Get, List, Update, Delete pods |

  ## Test plan
- [x] `poetry run pytest 'backend/blocks/test/test_block.py' -xvs` — all
new blocks pass the standard block test suite
  - [x] test all blocks manually

AgentMail Draft blocks — create, get, list, update, send, and delete drafts.
A Draft is an unsent message that can be reviewed, edited, and sent later.
Drafts enable human-in-the-loop review, scheduled sending (via send_at),
and complex multi-step email composition workflows.
