EmberTimer v1.1.0

v1.1.0 - Reworked top bar, GitHub-style heatmap, scheduled reports

• Top bar rework: current profile becomes a center dropdown (name-only items, disabled while running, empty-state tap goes to settings); a right-hand hamburger menu jumps straight to weekly/monthly reports with the matching tab preselected. The old chip row is gone.
• Heatmap: cells rounded to a uniform 2dp, dates before the first focus record render blank, month labels follow the GitHub convention (only on month-change columns).
• Weekly (Sunday 23:00) and monthly (last day 23:00) summary notifications on a dedicated channel - only when the period actually has focus time; tapping opens the report screen on the right tab. No new permissions.
• Unified motion: profile-name and today-total slide transitions, report week/month crossfade, empty-state expand, and cross-screen transitions - all still snap when the system "remove animations" setting is on.

Tests: 212/212 green. No new dependencies.
