drop the jsonBody workaround — the platform parses these bodies now

this plugin read ctx.req.json() directly because registerProxiedPrefix claimed
the whole of /api/caldav, so bodyParser skipped the plugin's OWN routes and every
field read as missing.

the platform's proxy takes a proxiedSubPath now, so this claims only
/api/caldav/_officer — what the sidecar actually answers — and /passwords and
/provision/ios get their bodies the ordinary way.

verified end to end: POST /api/caldav/passwords with a label came back with the
label, and _officer/collections still reaches the sidecar.

- *
- * `createSidecarProxy` registers `/api/caldav` with `registerProxiedPrefix`, which tells `bodyParser` to

- * so they get `{}` and every field reads as missing.
- *
- * Before the extraction these routes lived under `/api/dav`, a second top-level prefix that was not
- * proxied, so their bodies parsed. One prefix per plugin is the rule that ended that arrangement.
- *
- * Read here rather than fixed in the platform because the platform's rule is correct — the narrower fix
- * is for the proxy to register only the sub-path it actually serves (`_officer/*`), which is a change to
