More importantly if the server just accepts hashed passwords and stores them, then if you got ahold of a hashed password through a leak you could just use it directly to authenticate by modifying the client. The hashed password just becomes the password with one extra client-side step that you can trivially skip.

Salting is more about making it non-obvious which passwords map to which hashes so you can’t easily build tables of hashes for common passwords.

Sending the password to the server in “plain text” is fine over https, it’s a secure channel. Hashing isn’t meant to hide the password on the wire, it’s to prevent anyone with access to the database from learning what the passwords are.
