Support multiple comma-separated grids (VUCC) across SimpleFLE. Updated Logbook_model to accept vucc_grids and prefer it over single locator when present. Frontend changes: parse and detect single vs multiple grids, add Grid column to preview table, send both `locator` and `vucc_grids` to the save endpoint, tighten time regex, add qsotime variable, include X band in satellite mode handling, and clear satellite state when switching to a regular band. Documentation and help updated: improved syntax help and added full docs/SimpleFLE.md explaining grids, VUCC usage, satellite handling and other SimpleFLE features.
Introduces the ability to add comments to QSOs by enclosing text in angle brackets, updates the UI to display a new Comment column, and documents the feature in the syntax help. The JavaScript logic is updated to extract, display, and save comments with each QSO.
Enhanced the syntax help and JavaScript logic to support satellite QSOs and gridsquares. Satellite contacts can now be entered using 'sat' or 'satellite' keywords, with automatic frequency/mode population from a satellite database. Gridsquares can be included with callsigns, and both features are now parsed, displayed, and saved in the QSO table and backend.
