feat(monday): add full Monday.com integration (#4210)

* feat(monday): add full Monday.com integration with tools, block, triggers, and OAuth

Adds a comprehensive Monday.com integration:
- 13 tools: list/get boards, CRUD items, search, subitems, updates, groups, move, archive
- Block with operation dropdown, board/group selectors, OAuth credential, advanced mode
- 9 webhook triggers with auto-subscription lifecycle (create/delete via GraphQL API)
- OAuth config with 7 scopes (boards, updates, webhooks, me:read)
- Provider handler with challenge verification, formatInput, idempotency
- Docs, icon, selectors, and all registry wiring

* fix(monday): cast userId to string in deleteSubscription fallback

The DeleteSubscriptionContext type has userId as unknown, causing a
TypeScript error when passing it to getOAuthToken which expects string.

* fix(monday): escape string params in GraphQL, align deleteSubscription with established patterns

- Use JSON.stringify() for groupId in get_items.ts (matches create_item.ts
  and move_item_to_group.ts)
- Use JSON.stringify() for notificationUrl in webhook provider
- Remove non-standard getOAuthToken fallback in deleteSubscription to match
  Airtable/Webflow pattern (credential resolution only, warn and return on failure)

* fix(monday): sanitize columns JSON in search_items GraphQL query

Parse and re-stringify the columns param to ensure well-formed JSON
before interpolating into the GraphQL query, preventing injection
via malformed input.

* fix(monday): validate all numeric IDs and sanitize columns in GraphQL queries

- Add sanitizeNumericId() helper to tools/monday/utils.ts for consistent
  validation across all tool body builders
- Apply to all 13 instances of boardId, itemId, parentItemId interpolation
  across 11 tool files, preventing GraphQL injection via crafted IDs
- Wrap JSON.parse in search_items.ts with try-catch for user-friendly
  error on malformed column filter JSON

* fix(monday): deduplicate numeric ID validation, sanitize limit/page params

- Refactor sanitizeNumericId to delegate to validateMondayNumericId
  from input-validation.ts, eliminating duplicated regex logic
- Add sanitizeLimit helper for safe integer coercion with bounds
- Apply sanitizeLimit to limit/page params in list_boards, get_items,
  and search_items for consistent validation across all GraphQL params

* fix(monday): align list_boards limit description with code (max 500)

The param description said "max 100" but sanitizeLimit caps at 500,
which is what Monday.com's API supports for boards. Updated both the
tool description and docs to say "max 500".
