[pmg-devel] [RFC pmg-yew-quarantine-gui 2/2] main view: handle optional quarantine action in spamreport links

[Stoiko Ivanov <s.ivanov@proxmox.com>]

Our html verbose spamreports have included links for each possible
action for each mail (delete, deliver, blocklist, welcomelist) in the
action GET parameter. Currently the yew-based mobile view does not
handle those actions.

This patch adds the functionality by issueing a POST request in the
view function if the a cselect (id) and action parameter are present.

I tried adding the same call to the update function, but it seems the
update function does not get the query-string after a login, or was not
called in my tests.

Big thanks to Dominik for walking me through our yew framework and
providing other valuable suggestions!
