* Allow to align the working plane on selected edge + face of a same object, which aligns the plane with the face, but positions it on the edge (the WP is positioned on the edge's first vertex, the WP's X axis is aligned with the edge, and the face's center point provides the third point to define the plane)
* Added a "Recenter" in-command shortcut. This moves the WP to be centered on the current snap position (the WorkingPlane snap button is taken into account, so one can only move the WP in the same plane or not).
* [Start] ensure user's preferred unit schema is retained after restart of application
* [App] use consistent schema names throughout the application
* [pre-commit.ci] auto fixes from pre-commit.com hooks

- Positioning was calculated using `boundingRect` while `transformOriginPoint` was set according to `tightBoundingRect`, causing mismatch when `QGIDatumLabel` contains more than text (eg. shapes around text). Now `transformOriginPoint` and positioning calculated according to `tightBoundingRect`, and setting `transformOriginPoint` of `QGIDatumLabel` are handled by itself. This fixes an issue where the gap between dimension lines and text varied depending on dimension's angle.
- `m_lineWidth` was set in multiple locations, causing confusion and bug introduction
- If `X` or `Y` property changed, the remaining changed properties were not handled due to using `if else` rather than `if` for property change checking. This became an issue due the above mentioned simplification of `m_lineWidth` setting: if `X` or `Y` had changed (upon document restore).
- Center position was uneededly saved in variables `posX` and `posY` when it could be calculated on demand using `tightBoundingRect`. Removing this uneeded state simplfies code and lowers the risk of bug introduction due to lack of updating state.
The 'CTRL to snap' option is not the default, it should therefore not be included in the tooltips.
Additionally:
* Some obsolete info was removed.
* Some minor improvements,
