feat: increase message size from 30 to 50 mb gross

this PR allows attachments and videos of about 38 mb net (50 mb gross).

once relays are sufficiently updated, core will pick up the new default
(core currently uses 18 mb only, an old default of non-chatmail-era)

this is quite some boost in quality or video length, roughly a doubling,
which still being reasonably to overall storage
(with this PR we alllow a single message taking up to 1/10th of storage -
when chatmail was started, this was even 1/3rd.
note, that too large files will be deleted, but there will add a pre-message still)
