Move all login and account creation page labels to be above inputs (#29432)

There are a few inconsistencies within Gitea and this PR addresses one
of them. This PR updates the sign-in page layout, including the register
and openID tabs, to match the layout of the settings pages
(/user/settings) for more consistency.

This PR updates the following routes:
`/user/login`
`/user/sign_up`
`/user/login/openid`
`/user/forgot_password`
`/user/link_account`
`/user/recover_account`
