Subject: [PATCH] feat: add Calendar, Timesheet, and MiniTimer views

Calendar shows weekly time-block layout with hour rows, entry positioning,
current time indicator, and week navigation. Timesheet provides a weekly
grid with project/task rows, day columns, totals, and add-row functionality.
MiniTimer is a minimal always-on-top timer display for the floating window.
