feat: auto-save signer with status 0 when added

Automatically saves the signer to the server with status 0 (draft)
when the user adds a new signer through the Add Signer dialog.
This eliminates the need for a separate manual save action after
adding each signer.

The PATCH request is sent to /apps/libresign/api/v1/request-signature
with status: 0 immediately after the signer is added to the local state.
