Remove Plaid integration from documentation and API (#304)

This PR removes all Plaid integration support from the codebase,
including documentation, API specifications, and code examples.

## Summary
Plaid integration has been completely removed from the platform. This
includes all user-facing documentation, API endpoint definitions, and
code examples across multiple product areas (ramps, payouts, rewards,
and global P2P).

## Key Changes

- **Removed documentation files:**
- `mintlify/ramps/accounts/plaid.mdx` - Comprehensive Plaid integration
guide for ramps
- `mintlify/payouts-and-b2b/depositing-funds/plaid.mdx` - Plaid guide
for payouts
- `mintlify/rewards/developer-guides/plaid.mdx` - Plaid guide for
rewards
- `mintlify/global-p2p/managing-accounts/plaid.mdx` - Plaid guide for
global P2P
- `mintlify/snippets/plaid-integration.mdx` - Shared Plaid integration
snippet

- **Removed API specifications:**
  - `/plaid/link-tokens` POST endpoint for requesting Plaid Link tokens
- `/plaid/callback/{plaid_link_token}` POST endpoint for submitting
public tokens
- All associated OpenAPI schema definitions (`PlaidLinkTokenRequest`,
`PlaidLinkTokenResponse`, `PlaidCallbackRequest`,
`PlaidCallbackResponse`)
  - OpenAPI path files in `openapi/paths/plaid/`
  - OpenAPI schema files in `openapi/components/schemas/plaid/`

- **Updated documentation references:**
- Removed Plaid links from external accounts guides across all product
areas
  - Updated platform capabilities documentation to remove Plaid mentions
- Updated account model and transaction lifecycle docs to remove
Plaid-specific references
- Updated navigation structure in `mintlify/docs.json` to remove Plaid
pages

## Implementation Details

The removal is comprehensive and affects both the OpenAPI specification
files (modular YAML structure) and the consolidated OpenAPI definitions.
All references to Plaid in code examples and best practices have been
removed, with some documentation updated to reflect alternative
approaches (e.g., "debit cards" instead of "Plaid-linked accounts").
