Rewrite tooltip UI for efficiency and Vue 3.0 #230

- Introduce a new UI component for tooltips.
- Fix tooltip arrow misalignment issues in code download/execution
  instructions dialogs.

Reasons for dropping `v-tooltip` dependency:

- Lack of support for Vue 3.0, which blocks migration to Vue 3.0 (see
  #230).
- Inability to render HTML content that's required for privacy.sexy.
- Inefficient, adding an extra 162.48 KB to the production bundle for
  web distribution (tested using `npm run build -- --mode production`).

Advantages of adopting `floating-ui` (Floating UI):

- Compatibility across multiple Vue versions including 2.0, 2.7, and 3.0.
- Reduced boilerplate resulting in cleaner, more maintainable code.
- Efficient position recalculations without reinventing the wheel.
