alerter: Replace v-tooltip with standard title

The `v-tooltip` attribute-based component has a bug: it is never eliminated once instantiated, and as the alerts list is regenerated for every new alert, the tooltip component was accumulating in an exponential way, leading to a crash in the whole application.

For the moment a simple `title` attribute is used, but it's not an ideal solution, as it takes some hovering time to be activated. A better solution involves creating/importing a new tooltip component that doesn't have the same bug or to expand the alert space to fit the text during hovering.
