feat(frontend): upgrade linked fields selector

[ivanskv2000]

✨ Overview

This PR significantly upgrades the event management experience by introducing a sleek, paginated interface for linking fields and standardizing form behavior across the application. It also addresses critical developer experience issues with Docker synchronization.

Key Changes:

1. LinkedFieldsSelector Upgrade

• New Interface: Replaced the simple checkbox list with a professional TanStack Table-based interface.
• Improved Interaction: Added a full-width search bar for instant filtering.
• Paginated View: Implemented compact 5-row pagination to maintain a clean form layout.
• Standardized Styling: ID and header formatting now strictly follow project-wide patterns (removing excessive custom formatting).
• "Select All" Logic: Added a global checkbox that toggles all filtered rows across all pages.
• Fixed Layout: Disabled column hiding to ensure the selector remains predictable and stable.

2. Security & UX (Form Attributes)

• Password Manager Fix: Added autocomplete="off" and unique name attributes to all metadata inputs in EventForm, FieldForm, TagForm, and the field search bar. This prevents password managers from incorrectly identifying these as login fields.
• Standardized Auth Forms: Verified and maintained correct autocomplete values for LoginForm and SignupForm.

3. Core Component & Layout Improvements

• DataTable Enhancements: Added hideHeader prop support and refined meta.class application to ensure reliable column truncation.
• Responsive Layout: Relaxed the EventCreatePage card width to max-w-2xl to better accommodate the new table-based selection interfaces.
• EventForm Reactivity: Refactored field selection to use v-slot="{ componentField }" pattern, ensuring perfect synchronization with vee-validate state.

4. Developer Experience

• Docker HMR Fix: Enabled file polling in vite.config.ts to resolve issues where local changes were not propagating to the Docker container on macOS.
