System-wide webhooks (#10546)

* Create system webhook column (and migration)

* Create system webhook DB methods

Based on the default webhook ones

* Modify router to handle system webhooks and default ones

* Remove old unused admin nav template

* Adjust orgRepoCtx to differentiate system and default webhook URLs

* Assign IsSystemWebhook when creating webhooks

* Correctly use booleans for IsSystemWebhook

* Use system webhooks when preparing webhooks for payload

* Add UI and locale changes

* Use router params to differentiate admin hook pages

* Fix deleting admin webhooks and rename method

* Add clarity to webhook docs

* Revert "Remove old unused admin nav template"

This reverts commit 191a20a7389fe5f6256b0ad6aafd04b9b0e295c5.
