FCCalendar component styling is not consistent with library

[kaseyvee]

Describe the bug
The FCCalendar component styling does not align with ui-components, still using Full Calendar's default styling.

Expected behavior

1. Colours from theme should be used.
2. Dropdown should be used for different views (month/week/day).
3. Tasks on month and week view should be readable (either scroll or show first letters/words of task with ellipses).
