Feature/use confirm composable

[XanderVertegaal]

We want an easy way to create 'Yes/No' confirmation modals in MyResearch, so I stole ripped borrowed this from DIAPP. Technically, it also exposes useMountComponent, which I will document in a future PR.

[Copilot]

Pull request overview

Adds a new useConfirm composable (and underlying mounting helper + dialog component) to enable programmatic “Yes/No” confirmation modals, along with documentation updates in the Nuxt docs app.

Changes:

• Introduces useConfirm and useMountComponent composables to mount and control a confirmation dialog programmatically.
• Adds BSConfirmDialog (built on BSModal) and exposes the new composables via the library’s composables entrypoint.
• Adds a docs page + nav entry, and tweaks Nuxt/Vite config for the docs app.
