Fetch dynamic dropdown options for a step's field

Mirrors every ‘Refresh’ dropdown in the Studio Setup tab. Used to resolve human references like ‘#general’ or ‘Contacts module’ into the actual identifiers the action config requires. Always ask the user to pick from the response — never silently auto-select, even when only one option exists.

Per-app supported kind values:

Slack: channels, private_channels, users
Zoho CRM / Freshworks / Salesforce / Microsoft Dynamics: modules, module_fields (params.module), records (params.module)
Airtable: bases, tables (params.base_id), fields (params.base_id, table_id), records (params.base_id, table_id)
Apify: actors, tasks
Gmail: labels, messages
Google Calendar: calendars, events (params.calendar_id)
Google Sheet: spreadsheets, worksheets (params.spreadsheet_id), columns (params.spreadsheet_id, worksheet_title)
Notion: databases, pages, database_properties (params.database_id), users
Twilio: phone_numbers
Logic (builtin, no connection needed): operators, joiners, delay_units
Tables (builtin, no connection needed): tables, columns (params.table_id), operators, operators_for_type (params.type), aggregates, order_directions
Telegram: returns 422 — Bot API has no list endpoint
