Closes#133.
`updateEvent`, `destroyEvent` and `rsvp` took an id and sent it. The
`baseEventId ?? id` that made them hit the series lived at four call
sites instead, and every one of them happened to be right.
That was backstopped by the server until now. Through 0.16.19 a synthetic
id reaching `destroy` came back as "Deleting synthetic ids is not yet
supported" and the user saw a toast. 0.16.20 accepts it and removes one
date instead, reporting success under a dialog that said "Delete all
occurrences?" - so a forgotten `??` became silent data loss rather than
an error.
The three methods now take the event and a required `scope`, and there is
exactly one place that turns an event into an id. A caller that wants the
series cannot get an occurrence by forgetting anything; a caller that
wants one occurrence has to say so.
`rsvp` takes the event rather than an id for the same reason, and no
longer looks it up: its patch is `participants/{key}/participationStatus`,
which is one of the pointers 0.16.20 *allows* on an occurrence, so aimed
at an instance it would quietly mean "only that day".
`findByUid` says in a comment that its query omits `expandRecurrences` on
purpose, since InviteCard hands the result straight to `destroyEvent`.
Guests added to an event vanished on save and no invitation was ever
sent. Not a guard in the editor, and nothing the server complained
about: ihasmail addresses a participant the way RFC 8984 does, with
sendTo and email, and Stalwart 0.16 keeps that address under
calendarAddress. Handed the RFC's spelling it stores the event, drops
the entire participant map, and reports success. Six shapes were tried
against a live 0.16.19, down to sendTo and roles alone; all six were
dropped, and patching a participant onto an existing event fails
outright with "Patch operation failed".
The same disagreement runs through two more properties. The organizer is
organizerCalendarAddress, not replyTo. A recurrence is a single
recurrenceRule, not a recurrenceRules array — and that one Stalwart
refuses honestly, with invalidProperties, so no recurring event could be
created at all and existing ones showed no repeat.
So writes now use Stalwart's names and reads accept either, since a
mailbox may hold events written by other clients. The mock now refuses
what the real server refuses and drops what it drops: advertising the
RFC spelling is exactly how this reached a live server unnoticed, the
same way the capability-placement bug did.
Verified against 0.16.19: participants, organizer and rule all survive a
create, an update and a re-read, with the roles kept as sent.
