UI: Fix ISO Hypervisor selection

[vishesh92]

Description

When deploying an Instance from an ISO in a multi hypervisor env, hypervisor type selection is ignored and it selects the first hypervisor from the list.
This PR fixes the above bug which was introduced in #10773

Apart from the above, this PR updates the older api to getAPI & postAPI for ZoneWizardRegisterTemplate.

Generated summary

This pull request introduces updates to improve the handling of hypervisor changes in the UI and refactors API calls in the ZoneWizardRegisterTemplate.vue component for better code clarity and consistency. The most important changes include modifying event handlers for hypervisor updates, refactoring API utility usage, and ensuring proper state updates.

UI Improvements for Hypervisor Handling:

• ui/src/views/compute/DeployVM.vue: Updated the @change-iso-hypervisor event to correctly update the form.hypervisor property instead of a standalone hypervisor variable.
• ui/src/views/compute/wizard/OsBasedImageSelection.vue: Simplified the @change event binding for handleIsoHypervisorChange by removing the unnecessary parentheses.
• ui/src/views/compute/wizard/OsBasedImageSelection.vue: Refactored the handleIsoHypervisorChange method to accept a hypervisor parameter directly, ensuring the emitted event receives the correct value.

API Refactoring:

• ui/src/views/infra/zone/ZoneWizardRegisterTemplate.vue: Replaced the generic api import with getAPI and postAPI for clearer intent in API calls.
• ui/src/views/infra/zone/ZoneWizardRegisterTemplate.vue: Updated registerTemplate to use postAPI and listOsTypes to use getAPI, aligning with the new API utility functions. [1] [2]
