misc: (studio) add support for url routing

[mschile]

• Closes Studio: [Delivery][Infrastructure] Add app level routing for Cypress studio #31000
• Closes Studio: [Infrastructure] Add app level routing for running/managing a single test in isolation #30996

Additional details

• Added the following url parameters when the user enters studio mode:
  • When modifying a test: testId and studio
    • e.g. https://example.cypress.io/__/#/specs/runner?file=cypress/e2e/1-getting-started/todo.cy.js&studio=&testId=r3
  • When adding a new test: suiteId, testId, and studio
    • e.g. https://example.cypress.io/__/#/specs/runner?file=cypress/e2e/1-getting-started/todo.cy.js&studio=&testId=r3&suiteId=r2
• The url parameters are removed when the user exits studio mode (either cancelling or saving)
• If the user is in studio mode and reloads the page, studio mode maintained (the pending commands are lost)
• Fixed an issue where if the save fails, we partially exited studio mode. Now, we will remain completely in studio mode but the error message is still not displayed (it wasn't shown previously either).

Updates to the EventManager class:

• packages/app/src/runner/event-manager.ts: Added a success handler for the studio:save event to call saveSuccess on the studioStore.
• packages/app/src/runner/event-manager.ts: Removed the studio property from the resolved run state to simplify the state management.

Modifications to the StudioControls.vue component:

• packages/app/src/runner/studio/StudioControls.vue: Added data-cy attributes to various elements for better testability and identification in Cypress tests. [1] [2] [3] [4] [5]

Improvements to the studio-store module:

• packages/app/src/store/studio-store.ts: Implemented URL parameter handling methods (_updateUrlParams, _removeUrlParams, _getUrlParams) to maintain the studio state across page reloads and navigation.

Steps to test
