Zeiterfassung + Visual-Polish (Keycap-Buttons, Space Grotesk)

Zeiterfassung
- Neue Tabelle time_entry mit started_at/ended_at/duration_seconds,
  optional todo_id/bezug, category-Enum (focus/meeting/break/admin/learning/other),
  description, day_entry_id-Verknüpfung. Partial-Unique-Index erzwingt
  max. einen aktiven Timer pro User.
- tRPC time-Router: now, start (stoppt aktiven automatisch), stop,
  listToday (Liste + Tagessumme), update, upsertManual (retroaktiv),
  delete, teamToday (personenübergreifend mit byCategory + aktivem
  Timer pro User).
- TopNav: persistente TimerPill links neben Streak. Quick-Picker mit
  heutigen ToDos, Kategorie-Auswahl und Freitext-Start. Live-Sekundenzähler.
- /heute: TimelineSection mit Edit/Delete pro Eintrag, ToDo-Bindung
  nachträglich änderbar, Block-nachtragen-Dialog. Pro ToDo-Zeile
  ▶-Start- und 🕐-Nachtrag-Button.
- /puls: TeamTimeSection mit aktiver Timer-Anzeige + Tagessumme +
  Kategorie-Breakdown pro User (refresh alle 30s, Live-Tick jede Sekunde).

Visual
- Space Grotesk als Hausschrift (selbst-gehostet, latin + latin-ext)
- Keycap-Button-Stil (Gradient + Druckeffekt) für primary/secondary/destructive
- Neue Helper-Module: format-duration, time-categories
