* Update Tempus Dominus to v6 (WIP)
* Re-add calendar input prepend container
* Normalize setting of default date values
* Migrate to Bootstrap 5 (WIP)
* Remove deprecated card columns implementation from dashboard
* Update BS5 data props
* Use Masonry layout for dashboard cards (for now)
This doesn't seem particularly ideal so may need a more involved refactor
* Update styles for Bootstrap 5 deprecations
* Remove resolutions crap
* Refactor deprecated BS4 classes
* Update list table styles
* Refactor deprecated jumbotron class usages
* Update close button structure
* Add `v2` branch to standard CI workflows
* No change if unsupported
* If supported, still auto-refresh at the selected frequency (if any),
but only if not hidden.
This is useful for always-on displays (e.g. a "baby clock"). Fixes#253
This commit adds a placeholder image for Child objects (in the future, hopefully, photo uploads will be added) and reworks the Dashboard view to look better when more than one child is in the database. There are also some minor tweaks to the Child detail view and one new Gulp requirement to improve the flow of copying static image assets from apps.
