feat: replace terminal dropdown with searchable datalist component

Enhanced the terminal server/container selection with a new searchable datalist component:

**Terminal View Changes:**
- Replaced `x-forms.select` with `x-forms.datalist` for server/container selection
- Added search functionality for filtering servers and containers
- Fixed form validation by adding hidden input for proper HTML5 validation
- Prevented error messages when clearing selection (sets to 'default')

**Datalist Component (Single Selection):**
- Implemented Alpine.js-powered dropdown with search functionality
- Added visual dropdown arrow that rotates when opened
- Proper entangle binding for wire:model support
- Keyboard support (Escape to close)
- Click outside to close behavior
- Disabled options filtering (skips disabled options)
- Consistent styling with input/textarea components

**Styling Improvements:**
- Explicit background colors: `bg-white` (light) and `dark:bg-coolgray-100` (dark)
- Proper ring border: `ring-1 ring-inset ring-neutral-200 dark:ring-coolgray-300`
- Focus states: `focus-within:ring-2 focus-within:ring-coollabs dark:focus-within:ring-warning`
- Text colors: `text-black dark:text-white`
- Added custom scrollbar styling for dropdown lists
- Wire:dirty state support for visual feedback
- Proper padding and spacing (`py-1.5`, `px-1`, `px-2`)

**Multiple Selection Mode:**
- Also updated for consistent styling and scrollbar support
- Added proper background colors and focus states
