Fix mobile dashboard sidebar and profile loader behavior

[RabbiIslamRony]

Summary

• Initialize the dashboard sidebar and profile uploader on DOM ready so mobile state is applied before full window.load.
• Centralize compact dashboard drawer open/close handling, shade behavior, resize state, nav-link closing, and aria-expanded / aria-hidden updates.
• Remove duplicate sidebar close/resize behavior from dashboardResponsive.js and keep it focused on dashboard/profile responsive layout updates.
• Keep the profile avatar uploader loading layer inside the uploader stacking context so it cannot overlay the mobile drawer.
• Improve the category select fallback state before Select2 initializes to reduce the short visual blink/jump.

Dashboard Fixes

• Compact dashboard sidebars now start collapsed before JS is fully ready, preventing the visible open-then-close flash on reload.
• The close button has a visible 32px hit area and icon color, with the drawer respecting the WordPress admin bar offset on logged-in mobile screens.
• The drawer closes from the close button, the shade/outside area, and compact nav-link clicks.
• Profile responsive setup now runs on initial load, tab switch, and resize.
• directorist-dashboard now depends on directorist-ez-media-uploader, which removes the uploader initialization race for the profile avatar field.

Select Fallback Fix

• The category search field keeps the native select visually closer to the final Select2 state while Select2 is initializing.
• The default category placeholder now matches the shorter final label, reducing the temporary text change users can see during initialization.

Verification

• node --check assets/src/js/public/components/dashboard/dashboardSidebar.js
• node --check assets/src/js/public/components/dashboard/dashboardResponsive.js
• node --check assets/src/js/public/components/profileForm.js
• php -l includes/asset-loader/scripts.php
• php -l templates/search-form/fields/category.php
• git diff --cached --check
• Agent Browser mobile checks at 516x642 on /dashboard/#dashboard_profile: reload starts with the sidebar collapsed, close icon is visible/clickable, shade and nav links close the drawer, and dashboard/avatar loaders do not remain over the sidebar.
• Agent Browser iPhone-sized check confirmed the close button and outside area receive pointer hits correctly.

Build Note

• Generated build assets were not included in this PR because this working copy already had broad unrelated generated asset churn. The committed source changes are scoped so a clean legacy build can be produced without mixing unrelated build output into this PR.
