chore: Update inbox view to perform better, added sidebar on inbox views (#12077)

# Pull Request Template

## Description

This PR includes improvements to Inbox view:

1. **Update the route to `:type/:id`**
Previously, we used `notification_id` in the route. This has now been
changed to use a more generic structure like `conversation/:id`, with
`type` set to `"conversation"`. This refactor allows future support for
other types like `contact`, making the route structure more flexible.
It also fixes a critical issue: when a notification is open and a new
notification arrives for the same conversation, the conversation view
used to close unexpectedly. This issue is now resolved.

2. **Migrate components from Options API to Composition API**
Both `InboxList.vue` and `InboxView.vue` have been updated to use the
Composition API with `<script setup>`.

3. **Auto-scroll inbox item into view when navigating**
When navigating through `InboxItemHeader`, the corresponding inbox item
now automatically scrolls into view and load more notifications
