Sign merges, CRUD, Wiki and Repository initialisation with gpg key (#7631)
This PR fixes #7598 by providing a configurable way of signing commits across the Gitea instance. Per repository configurability and import/generation of trusted secure keys is not provided by this PR - from a security PoV that's probably impossible to do properly. Similarly web-signing, that is asking the user to sign something, is not implemented - this could be done at a later stage however.

## Features
- [x] If commit.gpgsign is set in .gitconfig sign commits and files created through repofiles. (merges should already have been signed.)
- [x] Verify commits signed with the default gpg as valid
- [x] Signer, Committer and Author can all be different
    - [x] Allow signer to be arbitrarily different - We still require the key to have an activated email on Gitea. A more complete implementation would be to use a keyserver and mark external-or-unactivated with an "unknown" trust level icon.
- [x] Add a signing-key.gpg endpoint to get the default gpg pub key if available
    - Rather than add a fake web-flow user I've added this as an endpoint on /api/v1/signing-key.gpg
    - [x] Try to match the default key with a user on gitea - this is done at verification time
- [x] Make things configurable?
    - app.ini configuration done
    - [x] when checking commits are signed need to check if they're actually verifiable too
- [x] Add documentation

I have decided that adjusting the docker to create a default gpg key is not the correct thing to do and therefore have not implemented this.

Gary Kim f1c414882c Add Ability for User to Customize Email Notification Frequency (#7813)
* Add Backend Logic for Toggling Email Notification

This commit adds the backend logic for
allowing users to enable or disable email
notifications. The implementation ensures
that only issue notification emails get disabled
and important emails are still sent regardless
of the setting.

The UI to toggle this setting has not yet been
implemented.

* Add UI and complete user email notification enable

This commit completes the functionality to allow
users to disable their own email notifications.
