feat: Advanced Search Backend (#12917)
## Description

Implements comprehensive search functionality with advanced filtering
capabilities for Chatwoot (Linear: CW-5956).

This PR adds:
1. **Time-based filtering** for contacts and conversations (SQL-based
search)
2. **Advanced message search** with multiple filters
(OpenSearch/Elasticsearch-based)
- **`from` filter**: Filter messages by sender (format: `contact:42` or
`agent:5`)
   - **`inbox_id` filter**: Filter messages by specific inbox
- **Time range filters**: Filter messages using `since` and `until`
parameters (Unix timestamps in seconds)
- **90-day limit enforcement**: Automatically limits searches to the
last 90 days to prevent performance issues

The implementation extends the existing `Enterprise::SearchService`
module for advanced features and adds time filtering to the base
`SearchService` for SQL-based searches.

## Technical Implementation

### SQL-Based Search (Contacts, Conversations, Articles)
- Uses PostgreSQL `ILIKE` queries by default
- Optional GIN index support via `search_with_gin` feature flag for
better performance
- Time filtering uses `last_activity_at` for contacts/conversations
- Returns paginated results (15 per page)

### Advanced Search (Messages)
- Powered by OpenSearch/Elasticsearch via Searchkick gem
- Requires `OPENSEARCH_URL` environment variable
- Requires `advanced_search` account feature flag
- Enforces 90-day lookback limit via
`Limits::MESSAGE_SEARCH_TIME_RANGE_LIMIT_DAYS`
- Validates inbox access permissions before filtering
- Returns paginated results (15 per page)

---

## Type of change

- [x] New feature (non-breaking change which adds functionality)
- [x] Enhancement (improves existing functionality)

---

## How Has This Been Tested?

### Unit Tests
- **Contact Search Tests**: 3 new test cases for time filtering
(`since`, `until`, combined)
- **Conversation Search Tests**: 3 new test cases for time filtering
- **Message Search Tests**: 10+ test cases covering:
  - Individual filters (`from`, `inbox_id`, time range)
  - Combined filters
  - Permission validation for inbox access
  - Feature flag checks
  - 90-day limit enforcement
  - Error handling for exceeded time limits

### Test Commands
```bash
# Run all search controller tests
bundle exec rspec spec/controllers/api/v1/accounts/search_controller_spec.rb

# Run search service tests (includes enterprise specs)
bundle exec rspec spec/services/search_service_spec.rb
```

### Manual Testing Setup
A rake task is provided to create 50,000 test messages across multiple
inboxes:

```bash
# 1. Create test data
bundle exec rake search:setup_test_data

# 2. Start OpenSearch
mise elasticsearch-start

# 3. Reindex messages
rails runner "Message.search_index.import Message.all"

# 4. Enable feature flag
rails runner "Account.first.enable_features('advanced_search')"

# 5. Test via API or Rails console
```

## Additional Notes

### Requirements
- **OpenSearch/Elasticsearch**: Required for advanced message search
  - Set `OPENSEARCH_URL` environment variable
  - Example: `export OPENSEARCH_URL=http://localhost:9200`
- **Feature Flags**:
  - `advanced_search`: Account-level flag for message advanced search
- `search_with_gin` (optional): Account-level flag for GIN-based SQL
search

### Performance Considerations
- 90-day limit prevents expensive long-range queries on large datasets
- GIN indexes recommended for high-volume search on SQL-based resources
- OpenSearch/Elasticsearch provides faster full-text search for messages

### Breaking Changes
- None. All new parameters are optional and backward compatible.

### Frontend Integration
- Frontend PR tracking advanced search UI will consume these endpoints
- Time range pickers should convert JavaScript `Date` to Unix timestamps
(seconds)
- Date conversion: `Math.floor(date.getTime() / 1000)`

### Error Handling
- Invalid `from` parameter format is silently ignored (filter not
applied)
- Time range exceeding 90 days returns `422` with error message
- Missing `q` parameter returns `422` (existing behavior)
- Unauthorized inbox access is filtered out (no error, just excluded
from results)
