Add templates, per-set tracking, and float weight support

- Rename tables with workout_ prefix, add workout_templates and
  workout_template_exercises tables
- Add bw_relative flag to exercises for body-weight-relative display
- Store reps, weight, and rest_time as per-set comma-separated TEXT
  in session exercises (rest_time is optional/nullable)
- Support float weight with one decimal place
- Add template CRUD and template-to-session logging flow
