The updateCompose() function now correctly detects SERVICE_URL_* and
SERVICE_FQDN_* variables regardless of whether they are defined in
YAML list-style or map-style format.
Previously, the code only worked with list-style environment definitions:
```yaml
environment:
- SERVICE_URL_APP_3000
```
Now it also handles map-style definitions:
```yaml
environment:
SERVICE_URL_TRIGGER_3000: ""
SERVICE_FQDN_DB: localhost
```
The fix distinguishes between the two formats by checking if the array
key is numeric (list-style) or a string (map-style), then extracts the
variable name from the appropriate location.
Added 5 comprehensive unit tests covering:
- Map-style environment format detection
- Multiple map-style variables
- References vs declarations in map-style
- Abbreviated service names with map-style
- Verification of dual-format handling
This fixes variable detection for service templates like trigger.yaml,
langfuse.yaml, and paymenter.yaml that use map-style format.
