chore: merge 0.2.2 hotfix back into main

[jsenecal]

Summary

• Brings the 0.2.2 hotfix (issue [Bug]: Structure Location does not show maps after a clean install #52: geometry map widget blank on NetBox 4.6 / Django 6.0) back into main.
• Advances the version baseline to 0.2.2; the in-flight features stay under [Unreleased] for the next (0.3.0) release.

Changes

• netbox_pathways/forms.py: PathwaysMapWidget.get_context re-exposes the id/name/geom_type template-context vars that Django 6.0 dropped from BaseGeometryWidget.
• tests/test_map_widget.py: regression tests for the widget render.
• CHANGELOG.md: new ## [0.2.2] - 2026-06-30 section (Fixed [Bug]: Structure Location does not show maps after a clean install #52); [Unreleased] features preserved.
• README.md, docs/index.md: NetBox 4.6 / Django 6.0 compatibility notes.
• version bump 0.2.1 -> 0.2.2 (merged from release/0.2.2).

Testing

• ruff check passes
• ruff format --check passes
• pytest passes locally (459 + 3 new, on NetBox 4.6.3 / Django 6.0.6)
• New/changed behavior covered by tests
• Migration applied cleanly (n/a -- no schema change)
• Docs updated (README, CHANGELOG, docs/)
