Add module overrides with showtitle, fix footer and a11y positioning

New module overrides with showtitle support:
- mod_stats, mod_feed, mod_wrapper, mod_whosonline, mod_users_latest

Footer CSS:
- Each footer module now stacks full-width (flex-direction: column)
- Remove hardcoded padding-right: 300px inline style
- Dynamic footer padding-right based on theme FAB and a11y toolbar

Accessibility toolbar positioning:
- Toolbar now sits to the right of the theme FAB (bottom-right area)
- Shifts automatically when theme FAB is enabled via CSS attribute
  selectors on body data attributes
