Pull request overview

Adds a new SendGrid provider module (send + webhook) and updates the console to better support provider configuration fields (password inputs + rate limit override shape).

Changes:

• Introduce a SendGrid WASM provider module with email sending, webhook parsing, and optional webhook signature verification.
• Add SendGrid-focused unit tests and module build/config scaffolding (Makefile, go.mod/go.sum, README).
• Update console integration setup to submit/consume the new rate_limit object shape and render schema fields with format: "password" as password inputs.

Thanks! I noticed that some files outside of the sendgrid implementation have been affected. Could you please check.

Could you check why these binaries have been changed?

Honestly, I can't find any reason why this happened, might be my go version, my git history said i didn't even push this
