debug: add detailed Sentinel container processing logging

Added comprehensive logging to track why applicationContainerStatuses
collection is empty in PushServerUpdateJob.

## Logging Added

### 1. Raw Sentinel Data (line 113-118)
**Logs**: Complete container data received from Sentinel
**Purpose**: See exactly what Sentinel is sending
**Data**: Container count and full container array with all labels

### 2. Container Processing Loop (line 157-163)
**Logs**: Every container as it's being processed
**Purpose**: Track which containers enter the processing loop
**Data**: Container name, status, all labels, coolify.managed flag

### 3. Skipped Containers - Not Managed (line 165-171)
**Logs**: Containers without coolify.managed label
**Purpose**: Identify containers being filtered out early
**Data**: Container name

### 4. Successful Container Addition (line 193-198)
**Logs**: When container is successfully added to applicationContainerStatuses
**Purpose**: Confirm containers ARE being processed
**Data**: Application ID, container name, container status

### 5. Missing com.docker.compose.service Label (line 200-206)
**Logs**: Containers skipped due to missing com.docker.compose.service
**Purpose**: Identify the most likely root cause
**Data**: Container name, application ID, all labels

## Why This Matters

User reported applicationContainerStatuses is empty (`[]`) even though
Sentinel is pushing updates. This logging will reveal:

1. Is Sentinel sending containers at all?
2. Are containers filtered by coolify.managed check?
3. Is com.docker.compose.service label missing? (most likely)
4. What labels IS Sentinel actually sending?

## Expected Findings

Based on investigation, the issue is likely:
- Sentinel is NOT sending com.docker.compose.service in labels
- Or Sentinel uses a different label format/name
- Containers pass all other checks but fail on line 190-206

## Next Steps

After logs appear, we'll see exactly which filter is blocking containers
and can fix the root cause (likely need to extract com.docker.compose.service
from container name or use a different label source).
