Allow browsing historical accomplishments.
Created a timeutils module, which contains all time-related logic, to
allow easier extension later (for when I'll be implementing timezones
and custom day-start hours)
show today's accomplishements on the main page
extract main.handle_accomplishment_submission function
handle adding new accomplishments to the database
add header and add accomplishment UI
extract .card css component
add Accomplishment model
