Missing time on --start error

[mstmob]

todo list --start before 2023-03-01 results in the following error:

It works as expected if the time is specified, i.e.: todo list --start before 2023-03-01T10:00

Proposal: The start parameter should fallback to a default time, i.e. "00:00:00".

Furthermore the --start parameter should be documented correctly:
Currently no [before|after] is described in the documentation and zsh completion.

Version: todoman, version 4.2.1

Indeed, we should allow dates here. I think _validate_start_date_param should return Tuple[bool, datetime] | Tuple[bool, date] | None (it currently returns Tuple[bool, datetime] | None).

The docs should also definitely reflect the before/after usage.
