Log presets feature (#3509)

* Log presets feature
- Add “Load Presets…” button in Logger → Log Filter (settings_dialog.ui)
- Implement LogPresetsDialog (table: Comment, Filter)
- Support add (+), multi-remove (−), load via button or double-click
- Persist presets via QSettings at logger_presets/entries (qt_ui.ini)
- Wire button to open dialog and set logFilterLineEdit
- Update CMakeLists.txt to include new dialog sources

* CLang fix

* CLang fix again

* Log Presets: checkbox selection + tri-state header

- Added first column with per-row checkboxes
- Implemented header checkbox with tri-state; click toggles select-all/none
- Synced checkboxes and row selection in both directions
- Header toggle also updates row selection to match
- Remove operates on checked rows; falls back to selected rows if none checked
- Load uses first checked row; falls back to first selected row
- Double-click row triggers the same action as Load
- Load button visible only when exactly one row is selected
- Remove button visible only when at least one row is selected
- Dialog opens with no selected rows and no focused buttons; focus set to table
- New rows start editing in the Comment column
- Serialization updated for new column indices; checkbox state not persisted
- Cleanups: removed unused include and empty helper; pruned temporary comments

* Clang

* Fix: tri‑state header checkbox visible and aligned

- Overlay real QCheckBox in header section 0 (tri‑state)
- Align with row checkboxes using SE_ItemViewItemCheckIndicator
- Reposition on header resize and geometry changes
- Header click + checkbox click toggle select‑all/none
- Tri‑state reflects per‑row checkbox states

* CLang
