Missing Ajv Schema Validation on users REST API endpoints

[Harshit2405-2004]

Description

The legacy users REST API endpoints currently lack explicit schema validation. Inputs are weakly typed or imperatively checked inside the handlers, which can lead to runtime regressions.

The following endpoints need to be formally typed and migrated using ajv via @rocket.chat/rest-typings:

• users.getAvatar
• users.deleteOwnAccount
• users.resetAvatar
• users.forgotPassword

Proposed Solution

1. Add TypeBox/Ajv JSON schemas to packages/rest-typings.
2. Export the typing boundaries.
3. Attach the validateParams option onto the API.v1.addRoute config block for these endpoints.

A fix for this issue has been implemented and is currently under review in PR #39222.

Nice, I found login/signup issues I believe is because of ajv, hope this fixes the issue
