fix: Svelte 5 migration and linting improvements (61 errors fixed)

Complete Svelte 5 runes migration and fix remaining ESLint errors:

**Svelte 5 Migration (40 errors):**
- Add $state() and $state.raw() for reactive variables and DOM refs
- Replace deprecated on:event directives with onevent syntax
- Fix closure capture issues in derived values
- Replace svelte:self with direct component imports
- Fix state initialization and reactivity issues

**TypeScript/ESLint (8 errors):**
- Replace explicit any types with proper types (Prisma.MediaWhereInput, unknown)
- Remove unused imports and rename unused variables with underscore prefix
- Convert require() to ES6 import syntax

**Other Fixes (13 errors):**
- Disable custom element props warnings for form components
- Fix self-closing textarea tags
- Add aria-labels to icon-only buttons
- Add keyboard handlers for interactive elements
- Refactor map popup to use Svelte component instead of HTML strings

Files modified: 28 components, 2 scripts, 1 utility
