This adds a `message` column to the `alert_rule_version` table. This follows the
pattern established for dashboards as closely as possible. A new type is
introduced internally for passing the new `message` field around in a type-safe
manner, but doing the same for the API types becomes very messy. In that case, a
new field is added with omitempty.
Note this PR is only:
- The column addition
- The "read" path; API for listing versions
Subsequent PRs will add code to actually set the message when updating rules.
Rules created in the new api makes the rule have no group in the database, but the rule is returned in the old group api with a sentinel group name formatted with the rule uid for compatiblity with the old api.
This makes the UI continue to work with the rules without a group, and the ruler will continue to work with the rules without a group.
Rules are not allowed to be created in the provisioning api with a NoGroup sentinel mask, but NoGroup rules can be manipulated through both the new and old apis.

What is this feature?
This PR introduces a new alert rule configuration option, keep_firing_for (Prometheus documentation).
keep_firing_for prevents alerts from resolving immediately after the alert condition returns to normal. Instead, they transition into a "Recovering" state and are not considered resolved by the Alertmanager. Once the recovery period ends (or after the next evaluation if it is bigger than keep_firing_for), the alert transitions to "Normal" if it doesn't start alerting again:
Before
+----------+ +----------+
| Alerting |---->| Normal |
+----------+ +----------+
-----
After
+----------+ +------------+ +----------+
| Alerting |----->| Recovering |---->| Normal |
+----------+ +------------+ +----------+
Why do we need this feature?
This feature prevents flapping alerts by adding a recovery period. This helps avoid false resolutions caused by brief alert
* add column guid to alert rule table and rule_guid to rule version table
+ populate the new field with UUID
* update storage and domain models
* patch GUID
* ignore GUID in fingerprint tests
* introduce new fields created_by in rule tables
* update domain model and compat layer to support UpdatedBy
* add alert rule generator mutators for UpdatedBy
* ignore UpdatedBy in diff and hash calculation
* Add user context to alert rule insert/update operations
Updated InsertAlertRules and UpdateAlertRules methods to accept a user context parameter. This change ensures auditability and better tracking of user actions when creating or updating alert rules. Adjusted all relevant calls and interfaces to pass the user context accordingly.
* set UpdatedBy in PreSave because this is where Updated is set
* Use nil userID for system-initiated updates
This ensures differentiation between system and user-initiated changes for better traceability and clarity in update origins.
