Refactor usage of tooltips for flexibility

This commit introduces a new Vue component to handle tooltips. It acts
as a wrapper for the `v-tooltip`. It enhances the maintainability,
readability and portability of tooltips by enabling the direct inclusion
of inline HTML in the tooltip components. It solves issues such as
absence of linting or editor support and cumbersome string
concatenation.

It also provides an abstraction layer that simplifies the switching
between different tooltip implementations, which would allow a smooth
migration to Vue 3 (see #230).
