Bump migration version to 262 and add Migration_tag_2_8_10 which updates the stored app version to 2.8.10 and forces the version info dialog by resetting the user option. The migration includes a down() to revert the version to 2.8.9. Also update L.Terminator.js to generate three longitude-shifted polygon copies (offsets -360, 0, +360) so the night/day terminator overlay tiles correctly across world copies when the map is zoomed out.
Adjust terminator/greyline visual style and default options. Changed colors to #4a6fa5 (stroke) and #001f3f (fill), increased stroke weight to 1.5, lowered fillOpacity to 0.18, and changed resolution from 2 to 1. These edits were applied both where the greyline is created in the footer view and in the L.Terminator default options to keep behavior and appearance consistent.
Add a day/night greyline (terminator) overlay to the dashboard map.
- New assets/js/leaflet/L.Terminator.js: a Leaflet polygon plugin that computes the solar terminator for a given time and exposes L.terminator().
- Load the terminator script in the footer and register a Greyline overlay layer with start/stop interval updates (refreshes every minute). Updates are managed when the overlay is added/removed or when the map unloads to avoid orphaned timers.
- Expose the greyline as a toggleable overlay in the map layer control and add markers to a dedicated markersLayer overlay (instead of adding them directly to the map).
- Add a user preference checkbox to application/views/user/edit.php (Enable Dashboard Map Greyline Layer) and wire saving/reading of the dashboard_map_greyline option in application/controllers/User.php and application/controllers/Dashboard.php. Default behavior is enabled when not set.
This change lets users enable/disable the visual day/night terminator on the dashboard map and ensures proper lifecycle handling for updates and marker layering.
