Scheduled - During this maintenance window we will upgrade The Things Stack Cloud to v3.12.2

We do not expect noticeable downtime during this deployment.

Here is the changelog since the current version v3.12.1:

### Added

- Contextual tooltips to form fields in the Console.
- C-Style uint32_t representation for end device address field.
- Gateway Configuration Server to the cluster package.
- This introduces a new config option `cluster.gateway-configuration-server` that needs to be set in multi-instance deployments.
- Uplink storage for integrations in the Application Server. The number of uplinks stored per end device may be configured via the config option `as.uplink-storage.limit`.
- LoRaCloud GLS multi frame request support.
- LoRaCloud GNSS request support.
- LoRaCloud WiFi request support.

### Changed

- Allow the LinkADRReq commands to lower the data rate used by the end devices.

### Fixed

- Occasional crashes in the ratelimit middleware.
- Handling of zero EUI CUPS update-info requests.
- Backend validation messages for some forms.
- Gateway downlink message previews not displaying correctly in the event view of the Console.
- Importing end devices from the Console would occasionally ignore some device MAC settings fields.
