refactor: migrate createEventDispatcher to Svelte 5 callback props

Migrate 5 components from Svelte 4 createEventDispatcher to Svelte 5 callback props:
- DropdownMenu.svelte (removed unused dispatcher)
- ProjectListItem.svelte (edit, togglePublish, delete events)
- PostListItem.svelte (edit, togglePublish, delete events)
- AlbumListItem.svelte (toggleDropdown, edit, togglePublish, delete events)
- InlineComposerModal.svelte (close, saved events + migrate export let to $props)

Updated parent components to use onevent={handler} syntax instead of on:event={handler}.
