feat(Templates): Custom Templates Tab Management

[Elaina-Lee]

Type of Change

• Bug fix
• Feature
• Other

Current Behavior

Tab will only be enabled when 1. enableWizard is true and 2. isWizardUpdating is not true.

• enableWizard is true when there are selected workflows, meaning tabs will be disabled when no workflows are selected
• isWizardUpdating is used to determine temporarily disabling tabs or setting spinner/disabling panel until initialization or deletion is complete
  To be coming: With each tab validation, we may turn the tab status to error

Impact of Change

• This is a breaking change.

Test Plan

• UI elements are still to be polished (i.e. tab icons will not be always in progress once validation is implemented)
• Validation tests will be added along with validation logic & UI in the next PR (error tab status is not fixed yet)
