Description
### Tasks
- [ ] Update and change the wording of the toggles in Notifications (top section). Most of the toggles stay the same action, some are moved to a different section.
- [ ] Change Global section to have a new heading and subtext copy
- [ ] Create default radio buttons in the "global' section which maps to current global options. We're removing "Noisy" as that will be replaced by Sound.
- [ ] Play a sound for (noisy checkboxes) section - adding call invitation from the previous "Other" section
- [ ] "Other" as a section to be checkboxes instead of radio buttons
- [ ] Mentions and Keywords: Remove Noisy update Visuals and copy
- [ ] Create email section & add emails that are available as checkboxes
- [ ] "Mark as unread" change visuals and copy to "Clear notifications"
- [ ] Reset to defaults: Introduce button (if possible)
- [ ] Add a banner to the top to tell existing users that their settings have changed
- [ ] Where an existing user has settings that do not map to this new layout, add "Custom" radio buttons. Once the user moves away from 'custom' it is no longer available to select. If the user changes their settings on a different client or device, 'custom' would appear if those new settings do not map to these new global settings
