feat: Add push-message UI on Messages page with tests && feat: Add message list filtering and in-app push UI

[AlliotTech]

• Add a “Push Message” action and dialog on the Messages page
  (only for app-specific views)

• Send messages using the application token, avoiding
  interceptor overwrite

• Add UI tests covering button visibility and send flow

• Add quick filters to the Messages page (search title/body
  and exact priority)

I'm sorry to hear that.

after reviewing all the issues related to the search feature, it's clear from the comments and reactions that many people are interested in this functionality. (In this PR, I only implemented a UI filter feature, avoiding any intrusive backend complexity.)

if someone is still interested in this filter function, here is the branch reference: https://github.com/AlliotTech/server/tree/feat/ui-search

Anyway, I have already removed the search functionality from this PR. The current PR now only includes the push message feature.

Thanks for the contribution. I've added some remarks in subcomments.

Thank you, I've already fixed it.
