A user reported an issue where generating a PDF export of completed services results in a 504 Gateway Timeout error. The issue occurs when attempting to export a large dataset for an extended time range.

Steps to Reproduce:

• Navigate to Services.
• Click on Export Services.
• Select a time range (e.g., 1st September – 13th October).
• Click PDF export.
• Observe the result — the system returns a 504 Gateway Timeout error.

Observed behavior:

• The export request times out when generating a large PDF file.
• Other export formats (e.g., Excel) work correctly, even for large queries.
• The issue appears to be related to query size or PDF generation time.

Expected behavior:

• Large data exports (including PDF format) should complete successfully without timeout errors.
• The system should be able to handle large queries efficiently — possibly by optimizing the generation process, implementing asynchronous exports, or introducing background job processing.
