🚸(frontend) generate shorter room IDs making URLs easier to share

UUID-v4 room IDs are long and uninviting. Shorter, custom room IDs
can enhance UX by making URLs easier to share and remember.

While UUID-v4s are typically used in database systems for their low
collision probability, for ephemeral room IDs, the collision risk of e+14
combinations is acceptable.

This aligns room IDs with Google Meet format.

Even if the 'slugify' function is not used anymore, I kept it.
