fix: allow members to use SSH keys for deployments without full access

[Siumauricio]

What is this PR about?

Members couldn't use admin-managed SSH keys for git-based deployments without having Access to SSH Keys permission, which also exposed the SSH Keys management panel. This was a regression introduced in v0.28.7 with the new RBAC system.

Added a new allForApps endpoint in the SSH key router that uses protectedProcedure (authenticated only, no permission check) and returns only sshKeyId and name. The git provider dropdowns now use this endpoint instead of all, so members can select SSH keys for their apps without needing access to the SSH Keys management panel.

Greptile Summary

Adds a new allForApps tRPC endpoint on the SSH key router using protectedProcedure (authentication only, no permission check) that returns only sshKeyId and name, scoped to the caller's active organization. Both git-provider dropdowns switch from sshKey.all to sshKey.allForApps, restoring the ability for members to select SSH keys for deployments without the SSH Keys management permission.

Confidence Score: 5/5

This PR is safe to merge — the fix is minimal, correct, and does not expose any sensitive SSH key material.

The new endpoint is properly scoped by organizationId (matching the existing all endpoint pattern), returns only non-sensitive fields (id and name, no private key material), and requires authentication via protectedProcedure. No P0 or P1 issues found.

No files require special attention.
