feat: add hideHeader prop to JobView, MailView, BrainView...

[luanfreitasdev]

This pull request introduces a new hideHeader prop to several Laravel-related view components and updates their usage in split pane mode to provide a cleaner UI by hiding redundant headers. It also includes improvements to the split pane logic and some UI refinements for consistency.

Split Pane and Header Handling Improvements:

• Added a hideHeader prop to JobView, BrainView, MailView, LogView, and QueriesView components, and updated their templates to conditionally render the header based on this prop. [1] [2] [3] [4] [5]
• Updated HomeView.vue to pass the hide-header prop to these components when displayed in split pane mode, ensuring headers are hidden in the split view for a less cluttered interface.

Split Pane Logic and State Management:

• Improved split pane state management by hiding the dragged screen when split is activated and restoring its visibility when the split is closed. [1] [2]
• Refactored split pane screen name handling in Screens.vue for more reliable split detection and usage.

UI Consistency and Layout Adjustments:

• Standardized padding and border styles for screen headers and group labels across the main and split views for a more consistent look. [1] [2] [3] [4] [5] [6]

General Component and Screen Handling:

• Expanded the list of built-in screens in Screens.vue and improved logic for determining environment screens.
• Moved the EnvironmentDropdown into a Teleport for better overlay management.
