feat: add configurable sidebar font sizes

Browse Source 
Add two new workbench settings for controlling font sizes in sidebars:
- workbench.sideBar.fontSize: Controls primary sidebar font size (6-32px)
- workbench.secondarySideBar.fontSize: Controls secondary sidebar font size

This improves accessibility by allowing users to independently scale sidebar
content without requiring full UI zoom or source code edits.

Implementation uses CSS custom properties for live updates without reload.
Default of 13px preserves existing behavior.

Based on rejected VS Code PR #270851 - rejected with "In this area we do not
accept PRs" despite 18 positive reactions and community support.
