Migrate the own user on connection and mute events to the generated OwnUserResponse

[gpunto]

Goal

Parse the own user carried by the connection and mute-notification events with the generated
OwnUserResponse, the first step into the event DTOs.

Part of AND-1291

Implementation

• Point me on ConnectedEventDto, NotificationMutesUpdatedEventDto and
  NotificationChannelMutesUpdatedEventDto at the generated model. Vendors OwnUserResponse, the only
  new model in the closure.
• Add its mapper to User, and a collecting adapter so the flattened custom fields land in custom.
• Keep deleted_at, latest_hidden_channels, revoke_tokens_issued_before and
  total_unread_count_by_team in extraData as well. The generated model declares them and the domain has
  no property for any of them, so without that they would stop reaching User.extraData.

Notes

The per-event user stays on DownstreamUserDto. The backend models the two separately: the per-event user
is UserResponse, whose devices are ignore_if_client_side, while me is OwnUserResponse, which does
carry them. Devices on me parse through the generated DeviceResponse, whose created_at and user_id
are always sent because /devices and me serialize the same payload type.

language goes from nullable to required. It is a plain non-pointer tag on the shared user fields, so it is
always sent. The own-user test fixture was missing it, along with unread_count and unread_threads; it now
has its own fixture rather than sharing the per-event user one, since the two shapes differ on the wire.

Testing

Mutation sweep over OwnUserResponse.toDomain: zero survivors across all 25 fields.

Device-probed the user produced by the startup connection.ok, after setting a custom field on it:
language, the custom field, the unread counters and 16 devices all came through.

Summary by CodeRabbit

• Bug Fixes
  • Connection and mute-update events now correctly parse the signed-in user’s account details, including language, unread counts, devices, mutes, and preferences.
  • Additional account fields are retained when processing these events, helping prevent user data from being lost.

Walkthrough

The change adds an OwnUserResponse model and Moshi adapter for own-user event payloads. Three event DTOs now use this model for me. A new mapper converts the response to User, with tests for parsing and field mapping.

Merge Risk: 🟡 Moderate · up to f9172

Connection and mute-notification events now require several own-user fields that were previously optional. If the server omits any of them, the event fails to parse, which could break connection setup or mute updates. The backend contract for these fields should be confirmed, or they should be made tolerant, before merging.

Extra data stays in the rear.

of omitted keys by making them nullable or assigning safe defaults; update
`OwnUserResponse.toDomain()` to apply appropriate fallbacks, such as an empty
