Add a webhook and settings when comments get reported above a certain threshold

[helderdb]

What does this PR do?

Adds a new webhook event COMMENT_REPORTED_THRESHOLD_REACHED emitted when a comment reaches a configurable report threshold. Includes:

• New event type & data schema (storyID, siteID, commentID, reportCount).
• Webhook listener dispatches to configured endpoints.
• Admin UI settings (in DSAConfigContainer) to configure reportedThreshold per tenant.
• GraphQL schema/resolvers for DSA configuration (dsa.reportedThreshold).
• Logic in comment services/actions to check & emit event on report addition.
• Updated WEBHOOKS.md docs.
• Test fixtures update.
• Updated translations for DSA reporting in admin (with the help of AI)

No related issues.

These changes will impact:

• commenters
• moderators
• admins (new DSA config section for report threshold)
• developers (new webhook event)

What changes to the GraphQL/Database Schema does this PR introduce?

• GraphQL: New DSAConfiguration input/output types with reportedThreshold: Int field. Mutations/queries updated in resolvers/DSAConfiguration.ts.
• DB: Added dsa.reportedThreshold to TenantSettings model (default 5).

Does this PR introduce any new environment variables or feature flags?

None.

@kabeaty Do I need to do anything else in order to get this merged?

Hi there, interesting feature, I have a few notes:

• is there a strong reason to group this setting under DSA settings? It doesn't seem to be related to EU Digital Services Act features, and maybe should be grouped with other webhook settings.
• we have generally avoided including computer generated translation files, preferring to allow a fluent speaker to contribute translations as they require them, falling back to en-us

[helderdb]

Thank you for the reply @tessalt !

• No particular reason, I figured it would be the best place to do it. Should I show the threshold setting in the webhook settings details when the COMMENT_REPORTED_THRESHOLD_REACHED is selected? Then we might also move that setting from tenant level to webhook level instead?
• Shall I revert the translation files I do not know the language of? I can do English and Dutch.

@tessalt Updated the translations & moved the setting for the threshold to the webhook itself. The input field appears when you select the COMMENT_REPORTED_THRESHOLD_REACHED webhook.

@kabeaty @tessalt anything left to do for this?
