feat(#761): Granular daily memory selection for flows

[saraichinwag]

Summary

Implements granular daily memory selection for flows, replacing the binary all-or-nothing approach with multiple selection modes.

Closes #761

Selection Modes

1. None - Don't include any daily memory (default)
2. Recent days - Include the past N days (max 90)
3. Specific dates - Pick individual days from a calendar/list
4. Date range - From date X to date Y
5. Entire months - Select whole months at once

Changes

Backend

• DailyMemorySelectorDirective (Priority 46) - injects selected daily files into AI context
• Flows.php - added get_flow_daily_memory() and updated update_flow_memory_files() to handle daily_memory config
• Api/Flows/Flows.php - updated REST endpoints to include daily_memory in GET/PUT responses

Frontend

• DailyMemorySelector.jsx - new React component with all selection modes
• MemoryFilesSelector.jsx - updated to include daily memory selector
• FlowMemoryFiles.jsx - updated to pass daily memory data
• Queries/mutations updated for new data format

Database Schema

Daily memory config stored in flow_config JSON:

{
  "memory_files": ["custom-file-1.md"],
  "daily_memory": {
    "mode": "recent_days",
    "days": 7
  }
}

Testing

1. Open a flow's Memory Files modal
2. Scroll to Daily Memory section
3. Try each selection mode
4. Save and verify the config persists
5. Run the flow and check logs for injected daily memory
