Format messages for consistency

- no full stop at the end of a report message title
- no word please (technical writers' rule)
- boot loader => bootloader
- unique report message ids
- fix typos
- add missing context where messages are too short and vague
- make TASK tense consistent
- ensure each Action has a TASK level log message
- ensure every Action prints what it's done
- add unit tests to lines reported by caplog as uncovered
