style: Fix checkdoc warnings in video-audio-recording.el

Resolved 6 checkdoc linting warnings:
- Added double spaces after periods in docstrings (Emacs convention)
- Changed "calls" to "call" in docstring (imperative form)

All linting checks now pass:
- checkdoc: ✓ No warnings
- make lint: ✓ Passes
- All 83 tests: ✓ Still passing

Also updated docs/sessions/refactor.org to be more generic/reusable.
