[pmg-devel] [PATCH pmg-api/pmg-gui] allow / in local part of pmg-email-address

The following patchset is a result of investigating a thread in our
community forum [0].

While I'd consider e-mail addresses with '/' in the local-part quite odd,
as so often smtp RFCs are quite liberal with what smtp servers (have to)
accept. Postfix happily accepts mails with '/' in the local-part, and
should they end up in the quarantine, it is currently not possible to
remove them (short of waiting for quarantine retention period).

the 4 places where we use the pmg-email-address format are:
* quarantine (pmail parameter)
* statistics (contact, receiver, sender detail views)
* fetchmail
* pbsconfig (username)

the first two are problematic in the sense that external sources might
cause a mail-address with '/' to get stored. pbsconfig stores a username
with '/' (which then fails since the repository verification does not
expect a '/' in the username/token), fetchmail accepts it (and stores its
config with all special characters escaped)
only the statistics api calls are problematic, since the detail views pass
the mail-address as path component (and the decoding inside pve-http-server
breaks the api call resolution) - addressing this is the main part of the
patchset.

It follows a similar series by Dominik for the user blocklists [1].

patch 1/5 for the api is a cleanup that caught my eye
patches 2+3 for the api could probably be squashed (happy to send a v2 for
this - but feel free to squash them if this gets applied as is)

tested it a bit on my setup (with a limited set of addresses in the
statistics database).
