chore: migrate Popover usages to Shadcn components (#45980)

## Problem

We have multiple Popover components

## Solution

- [x] migrate Popover usages to Shadcn components
- Migrated JSON and text editor in the `TableEditor` (inline row
edition)
  - Migrated the template popover in the logs explorer templates page
- [x] remove `_Shadcn_` suffix from Popover components (renaming +
prettier)

## Summary by CodeRabbit

* **Refactor**
* Unified popover implementation across the app and design system;
dropdowns, calendars, menus and tooltips now use a consistent popover
API with no visual or interaction changes.

* **Chores**
* Minor prop typing update for the logs date-picker to align with the
consolidated popover content type.
