remove 3 month option for topic timer
move relative time input inside the custom
date and time shortcut
make sure special options are always at the bottom
This PR adds a new relative-time component, that is an input box with a SK dropdown of minutes, hours, days, and months which outputs the duration selected in minutes. This new component is used in the time shortcuts list (used by bookmarks and topic timers) as a new Relative Time shortcut.
Also in this PR, I have made the "Auto-Close After Last Post" timer into a top level timer type in the UI, and removed the "based on last post" custom time shortcut.
This PR revamps the topic timer UI, using the time shortcut selector from the bookmark modal.
* Fixes an issue where the duration of hours/days after last reply or auto delete replies was not enforced to be > 0
* Fixed an issue where the timer dropdown options were not reloaded correctly if the topic status changes in the background (use `MessageBus` to publish topic state in the open/close timer jobs)
* Moved the duration input and the "based on last post" option from the `future-date-input` component, as it was only used for topic timers. Also moved out the notice that is displayed which was also only relevant for topic timers.
