fix: prevent duplicate services on image change and enable real-time UI refresh

This commit addresses two critical issues with Docker Compose service management:

## Issue 1: Duplicate Services Created on Image Change
When changing the image in a docker-compose file, the parser was creating new
ServiceApplication/ServiceDatabase records instead of updating existing ones.

**Root Cause**: The parsers used `firstOrCreate()` with `['name', 'image', 'service_id']`,
meaning any image change would create a new record.

**Fix**: Remove `image` from `firstOrCreate()` queries and update it separately after
finding or creating the service record.

**Changes**:
- `bootstrap/helpers/parsers.php` (serviceParser v3): Fixed in presave loop (lines 1188-1203)
  and main parsing loop (lines 1519-1539)
- `bootstrap/helpers/shared.php` (parseDockerComposeFile v2): Fixed null check logic
  (lines 1308-1348)

## Issue 2: UI Not Refreshing After Changes
When compose file or domain was modified, the Configuration component wasn't receiving
events to refresh its data, requiring manual page refresh to see updates.

**Root Cause**: The Configuration component wasn't listening for refresh events dispatched
by child components (StackForm, EditDomain).

**Fix**: Add event listeners and dispatchers to enable real-time UI updates.

**Changes**:
- `app/Livewire/Project/Service/Configuration.php`: Added listeners for `refreshServices`
  and `refresh` events (lines 36-37)
- `app/Livewire/Project/Service/EditDomain.php`: Added `refreshServices` dispatch (line 76)
- Note: `app/Livewire/Project/Service/StackForm.php` already had the dispatch

## Tests Added
- `tests/Unit/ServiceParserImageUpdateTest.php`: 4 tests verifying no duplicates created
- `tests/Unit/ServiceConfigurationRefreshTest.php`: 4 tests verifying event dispatching

All 8 new tests pass, and all existing unit tests continue to pass.
