Simplify backup timestamp display with raw TOML format and remove spacing

Replace timestamp parsing with direct display of start_time from backup TOML file to ensure timestamp always appears regardless of format. Remove empty line spacing above backup section for compact layout.

Changes:
- Remove parsed timestamp fields and use raw start_time string from TOML
- Display backup time directly from TOML file without parsing
- Remove blank line above backup section for tighter layout
- Simplify BackupData structure by removing last_run and next_scheduled fields

Version bump to v0.1.150
