Quick fuel entry now remembers the selected vehicle’s latest primary-fuel price and keeps that price stable when editing the total. Thanks to @matt-laird for PR #376.
- Refresh the saved price when switching vehicles, and clear it when no matching history exists.
- Exclude AdBlue and other fuel types from primary-fuel defaults; preserve recorded zero prices.
- Preserve zero-cost fill-ups in calculated totals and station price history.
- Keep vehicle defaults within the signed-in user’s accessible vehicles.
- Align quick-form controls while preserving dark mode and spacing for unit labels.
Validation: all 1,459 Python tests passed after merging #376 and again on the final v0.44.1 candidate. JavaScript regression checks and real-browser mobile/dark-mode checks passed. The tagged production workflow also passed its full test suite and published linux/amd64 and linux/arm64 images successfully.
