fix(omny): accept p-accounts as valid in TomoIDManager

bec.active_account is normally a p##### proposal account in
production, but _is_valid_eaccount() only matched e#####, causing
every real beamtime session to be silently rejected and fall back to
tomo ID 0 (skipping OMNY registration and PDF upload). Widen the
regex to accept both e- and p-accounts while still rejecting
test/gac-* accounts.
