Add event colors (Catppuccin Mocha) and read-only week view for users

Admins can now pick a color per event from a Catppuccin Mocha palette;
existing events default to blue. Colors flow through to both the admin
timeline and the new "Неделя" tab in the user view, which reuses the
admin's weekly grid in a read-only mode. Also reworks event blocks to
show a single-line "start–end title" so short events no longer overflow,
tidies the admin toolbar, and expands mobile responsiveness across both
frontends.
