Daniel Riera 49a555c2d9 [PM-27821]Add validation of extension origin for uses of window.postMessage (#17476)
* PM-27821 - Replace chrome.runtime.getURL() with BrowserApi.getRuntimeURL() for consistency
- Add extension origin validation for all window.postMessage calls
- Implement token-based authentication for inline menu communications
- Add message source validation (event.source === globalThis.parent)
- Add command presence validation (- Update notification bar to validate message origins and commands
- Add extensionOrigin property to services using postMessage
- Generate session tokens for inline menu containers (32-char random)
- Validate tokens in message handlers to prevent unauthorized commands

* Add explicit token validation

* only set when receiving the trusted initNotificationBar message

* await windowmessageorigin before posting to parent

* fix tests

* the parent must include its origin in the message for notification bar race condition

* reduce if statements to one block and comment

* extract parentOrigin from the URL and set windoMessageOrigin accordingly

* consolidate if statements

* add bar.spec file

* fix merge conflict
