The upload retry logic now checks file_record.processed_file_path first
(the GPT-suggested filename stored during finalization), before falling
back to legacy hash-based and original-filename-based path patterns.
This fixes the case where the processed file has a different name than
the original (e.g., '2023-10-01_Unknown.pdf' vs 'cable_graphic.pdf')
and the retry couldn't find the file on disk.

Both get_file_preview and download_file were ignoring the DB-stored
original_file_path and processed_file_path fields, instead relying on
local_filename (a temp path that may be gone) and guessing patterns for
the processed file. This caused "Processed file not found" and
potentially "Original file not found" in the /files/{id} view even when
the files existed at their stored paths.
- version=original: check original_file_path first, fall back to local_filename
- version=processed: check processed_file_path first, fall back to
hash/filename guessing patterns

- Update _compute_processing_flow to recognize process_with_ocr as the OCR
stage and remap legacy process_with_azure_document_intelligence log entries
for backward compatibility
- Normalize legacy OCR step name in _compute_step_summary log fallback
- Add process_with_ocr to REAL_MAIN_STEPS/REAL_STEPS in step_manager,
file_status, and file_queries (keeping legacy name for old DB entries)
- Update retry logic in api/files.py to retry failed OCR via process_with_ocr
(handles both step names as aliases)
- Fix process_document.py to log process_with_ocr as skipped (not azure step)
for the local text extraction path

- Add app/utils/ocr_language_manager.py: detects tessdata dir, downloads
missing .traineddata files via wget/curl from tessdata_fast GitHub repo,
pre-downloads EasyOCR models, exposes async background-thread helper
- TesseractOCRProvider.process() calls ensure_tesseract_languages() before
running pytesseract; raises clear error if languages remain unavailable
- EasyOCRProvider.process() logs informational message when models download
- app/main.py: calls ensure_ocr_languages_async() at startup
- app/utils/settings_sync.py: triggers language re-check after every
settings reload so UI changes take effect without container restart
- app/api/settings.py: adds POST /api/settings/install-ocr-languages
endpoint for on-demand language installation from the admin UI
- Dockerfile: adds wget for runtime tessdata downloads
- docs/ConfigurationGuide.md: documents automatic language download
- tests/test_ocr_language_manager.py: 29 unit tests

`GET /api/settings/{key}` was calling `validate_setting_key()` which raises
HTTP 404 for keys not in SETTING_METADATA. The test expects 200 with value=None
for unknown keys.
Added `validate_setting_key_format()` to `input_validation.py` that validates
only the key format without the SETTING_METADATA existence check. Updated
`get_setting` to use the format-only validator; POST/DELETE endpoints continue
using the full `validate_setting_key()` for write-side security.

- Add RequestSizeLimitMiddleware that checks Content-Length header
before request body is read: non-multipart requests capped at
MAX_REQUEST_BODY_SIZE (default 1 MB), multipart uploads capped at
MAX_UPLOAD_SIZE (default 1 GB). Returns HTTP 413 on violation.
- Register middleware in app/main.py
- Add max_request_body_size setting to app/config.py
- Fix ui_upload in files.py to check Content-Length early and read
in 64 KB chunks (bounded memory usage), removing the post-write
os.path.getsize check
- Document MAX_REQUEST_BODY_SIZE in .env.demo and ConfigurationGuide.md
- Mark SECURITY_AUDIT.md item #4 as resolved
- Add 9 tests in test_request_size_limit.py
- Update test_upload_file_too_large to use patch.object instead of
the now-unused os.path.getsize mock
Closes#173

- Add comprehensive logging to all pipeline retry branches (process_document, process_with_azure_document_intelligence, extract_metadata_with_gpt, embed_metadata_into_pdf)
- Add original_file_path as 3rd fallback for embed_metadata_into_pdf (checks: local_filename, processed_file_path, original_file_path, workdir/tmp fallback)
- Include all checked paths with existence status in 400 error responses for easier debugging
- Add enhanced logging to upload task retry path showing which processed file paths were checked
- Log successful file path when found
- Add comprehensive test suite covering new logging and fallback behavior
