docs(terms): require cause for suspension and termination

Section 13 let us suspend or terminate an account "with or without cause and
with or without notice". It is common boilerplate, but for a product whose pitch
is that you can hold your own footage and leave whenever you want, it reads as a
standing right to close a paying customer for no reason.

It replaces that with four defined grounds: material breach of the Terms with a
ten day cure period, no cure period for a repeated breach of the same
obligation; unlawful use, infringement of a third party's rights, or a security
risk, where we may act immediately; fees unpaid fourteen days past due after
notice; and legal compulsion.

Defined grounds need their counterparts, so the clause also carries what we owe
in return: suspension while we investigate comes with a duty to say why and to
restore access if the suspicion does not hold, terminating for any other reason
or discontinuing the Service or a plan takes thirty days notice and a refund of
prepaid unused fees, and User Content stays available for export for thirty days
after termination.

Section 6 had the same flavour and is softened to match, from removing content
"at our sole discretion" to where we reasonably determine it violates the Terms.

That refund promise contradicted Section 5 and the Refund Policy, which both say
every fee is non-refundable including unused months. The general rule exists to
stop buyer's remorse refunds, not to let us keep a prepaid year we cut short, so
Section 13 now overrides them explicitly and the Refund Policy states the same
exception rather than leaving the two pages to disagree.
