oktofeesh c15b2b3f66 fix(connectors): enforce WebDAV numeric string size limits (#15731) ...

## Summary
- Normalize WebDAV file-size metadata before applying the sync size
threshold.
- Enforce the same threshold for numeric string sizes in both document
sync and slim snapshot paths.
- Add focused WebDAV unit coverage for size parsing and over-threshold
skips.

## Why
Some WebDAV servers return file sizes from PROPFIND metadata as strings.
The previous threshold check only handled integer values, so oversized
files could still be downloaded and sent into the chunking pipeline.

Closes #15724.

## Validation
- `uv run --no-project --with pytest --with pytest-asyncio pytest
test/unit_test/data_source/test_webdav_connector_unit.py -q`
- `uvx ruff check common/data_source/webdav_connector.py
test/unit_test/data_source/test_webdav_connector_unit.py`
- `python -m compileall -q common/data_source/webdav_connector.py
test/unit_test/data_source/test_webdav_connector_unit.py`
- `git diff --check`
