fix(android): MeApi — move request bodies inline (project pattern)

a1b1eed moved the body data classes out of MyProfileWire.kt but the
MeApi.kt write didn't land (stale Read), so MeApi was still trying
to import them from models.wire where they no longer exist. Inline
them in MeApi.kt matching the AdminUsersApi / PlaylistsApi /
QuarantineApi pattern (where request bodies live alongside the
interface).
