randogoth 623505b9c8 Close the remaining M1 gaps
Eight items were still open at the end of M1: two integration tests that had
only been run by hand, and six known gaps.

Recurrence overrides now reach Google. Google addresses an exception through
the series rather than as an event of its own, so the master is sent first and
each override is then matched to its instance by original start time and
patched. Matching needs the two sides' spellings reduced to one key: iCalendar
writes a zoned local time, Google an absolute offset. An override matching no
occurrence is counted rather than forced — that means a stale RECURRENCE-ID
left behind by an edited RRULE, and inventing an event for it would put
something in the calendar the series does not contain.

Reading one component apart from another needed a view `properties` cannot
give: it flattens every VEVENT together, which is right for the UID a series
shares and wrong for an override, whose SUMMARY and the master's are then
indistinguishable. `Calendar::events` splits them.

A TZID now travels with the VTIMEZONE that defines it, derived from the zone's
own transition table as the yearly rule it implies. This changes the content
hash of every zoned recurring event, so the first cycle after this re-pushes
them.

A Google authorisation is filed under the account it was granted for rather
than the endpoint that asked for it, so two endpoints on one account no longer
need a login each. The account is read from the primary calendar's id, which
needs no scope beyond the calendar one already granted. Authorisations written
by the previous scheme are still honoured, and move across at the next login.

An unreachable Google endpoint no longer ends the cycle — one lapsed token used
to stop the CalDAV side too. It is named, only the aggregates depending on it
stand down, and the run exits non-zero so a partial cycle cannot pass for
success. The CalDAV leg cannot be narrowed the same way: pimsync is one process
covering every pair, so a failure does not say which pair it belongs to.

`--dry-run` now pulls for real, into a throwaway copy of the local mirrors and
through a pimsync configuration that only ever reads from a server. What it
reports is measured against the calendars as they are now rather than against
whatever the last real cycle left behind.

`calcalist prune` reports local mirrors of endpoints the configuration no
longer names, and removes them under --force.

The integration tests run against a real Radicale server and a real iCal feed:
convergence and idempotence, the dry run, prune, and the scheduling rule
asserted on the bytes that actually reached the server. The plan asked for an
SMTP sink for that last one; Radicale implements no RFC 6638 scheduling, so a
quiet SMTP port would have proved nothing about the transform.
