Redesign settings UI and log entries, add wb3 logo

- Settings: tab per star with mini-toggle + template count badge
- Templates: full-width textarea per template (not cramped columns)
- Filter mode: pill-cards instead of raw radio buttons
- Save button aligned right with border-top separator
- Log: card-based entries (rating pill, meta row, review/reply blocks)
- wb3.png logo, 160px on login, 40px in topbar with ring shadow
- Fix CSS variable names (--c-* → --line/--card/--text/--muted)
