feat: replace n8n_create_data_table with n8n_manage_datatable (10 actions)

Browse Source 
Replaces the single-purpose n8n_create_data_table tool with a comprehensive
n8n_manage_datatable tool covering all 10 n8n data table API endpoints:

Table operations: createTable, listTables, getTable, updateTable, deleteTable
Row operations: getRows, insertRows, updateRows, upsertRows, deleteRows

- Filter system with and/or logic and 8 condition operators
- Dry-run support for updateRows, upsertRows, deleteRows
- Pagination, sorting, and full-text search for row listing
- 9 new N8nApiClient methods for all data table endpoints
- Shared error handler and consolidated Zod schemas
- Comprehensive tool documentation with examples per action
- 36 handler tests + 18 API client tests

BREAKING: n8n_create_data_table removed. Use n8n_manage_datatable with
action="createTable" instead.

Based on work by @djakielski in PR #646.
