Implement Endpoint to Edit Post

[enddynayn]

Description
We need to implement a new PUT endpoint to allow to editing content of a specific post. This allows users to update their post without creating a new one,

Acceptance Criteria

• Add GET /v1/content/{type}/{contentHash}
• Ensure type and contentHash is required.
• Ensure authentication is required.
• Update the OpenAPI swagger documentation.

Technical Specs
Endpoint: PUT /v1/content/{type}/{contentHash}
Authentication: Required (tokenAuth)
Parameters:

• contentHash (string, required): The hash of the post content to be edited.
• type (string, required, "Broadcast" or "Reply"): The type of the post.

Request Body: Must match the EditPostRequest schema, requiring targetContentHash, targetAnnouncementType, and content.

Responses:

• 200 OK: The edited post details, matching the BroadcastExtended schema.
• 401 Unauthorized: Attempt to access the endpoint without authentication.

Fyi we have this endpoint already implemented inside content-publisher. Please take a look at https://github.com/AmplicaLabs/content-publishing-service/blob/main/apps/api/src/api.controller.ts#L88

@aramikm you are right. This endpoint is for the Gateway-api service that will proxy the call over to Content-publisher.
