* chore: Extract change-detection method to it's own helper
This doesn't really belong in `helpers/ssl.sh`. Moving to it's own helper script.
* chore: Co-locate related change-detection method from container startup
It seems relevant to migrate the related support during startup for the change detection feature into this helper.
I opted to move the call from `start-mailserver.sh` into the `_setup` call at the end for a more explicit/visible location.
* chore: Move `CHKSUM_FILE` into `helpers/change-detection.sh`
It belongs there, not in `helpers/index.sh`.
* chore: Revise inline documentation
* tests(fix): Ensure correct functionality
Presently `test/test_helper.bats` is using it's own `CHKSUM_FILE` instead of sourcing the var for the filepath.
`test_helper/common.bash` was calling a method to check for changes, but this helper may not correctly detect letsencrypt related changes as these are not ENV rely on, but global vars handled by `helpers/dns.sh`, so that should be run first like it is for `check-for-changes.sh`.
* tests(chore): Use `CHKSUM_FILE` var from helper
* chore: `addmailuser` should use `CHKSUM_FILE` var
* chore: Update `check-for-changes.sh` log message with correct path
Dovecot master accounts can now be configured in DMS via `setup.sh`.
A master account is useful for administration purposes, or to perform mailbox backups of every user account over IMAP.

* chore: Extract letsencrypt logic into methods
This allows other scripts to share the functionality to discover the correct letsencrypt folder from the 3 possible locations (where specific order is important).
As these methods should now return a string value, the `return 1` after a panic is now dropped.
* chore: Update comments
The todo is resolved with this PR, `_setup_ssl` will be called by both cert conditional statements with purpose for each better documented to maintainers at the start of the logic block.
* refactor: Defer most logic to helper/ssl.sh
The loop is no longer required, extraction is delegated to `_setup_ssl` now.
For the change event prevention, we retrieve the relevant FQDN via the new helper method, beyond that it's just indentation diff.
`check-for-changes.sh` adjusted to allow locally scoped var declarations by wrapping a function. Presently no loop control flow is needed so this seems fine. Made it clear that `CHANGED` is local and `CHKSUM_FILE` is not.
Panic scope doesn't require `SSL_TYPE` for context, it's clearly`letsencrypt`.
* fix: Correctly match wildcard results
Now that the service configs are properly updated, when the services restart they will return a cert with the SAN `DNS:*.example.test`, which is valid for `mail.example.test`, however the test function did not properly account for this in the regexp query.
Resolved by truncating the left-most DNS label from FQDN and adding a third check to match a returned wildcard DNS result.
Extracted out the common logic to create the regexp query and renamed the methods to communicate more clearly that they check the FQDN is supported, not necessarily explicitly listed by the cert.
* tests(letsencrypt): Enable remaining tests
These will now pass. Adjusted comments accordingly.
Added an additional test on a fake FQDN that should still be valid to a wildcard cert (SNI validation in a proper setup would reject the connection afterwards).

* added new `_log` function
With `_log`, the `_notify` method wa rendered obsolete. `_notify` was
not completely removed due to test failures in `check-for-changes.sh`.
The new `_log` function properly uses log levels such as `trace`,
`debug`, `info`, `warn` and `error`. It provides a cleaner solution
and renders `DMS_DEBUG` obsolete too (as only `_notify` depends on it).
* converted all helper script to new `_log` function
* converted all startup stacks to new `log` function
* `start-mailserver.sh` now uses new `_log` function
* final test and misc small script adjustments
* updated documentation
