john-okeefe dd621956b9 database: change reading_speed columns from DECIMAL to REAL ...

- Changed words_per_minute, pages_per_minute, total_reading_minutes from DECIMAL(6,2) / DECIMAL(8,2) to REAL
- REAL (pgtype.Float4) is sufficient for reading statistics and simplifies Go code
- No precision loss for typical reading speed values (200-400 wpm, 0.5-3.0 pages/min)
