feat: Add inline creation modals for filament and vendor (#1)

When creating a spool, users can now create a new filament directly
from the filament dropdown without leaving the page. Similarly, when
creating a filament, users can create a new vendor inline.

New components:
- VendorCreateModal: Simple modal for quick vendor creation
- FilamentCreateModal: Modal with essential fields + nested vendor creation

Changes:
- Added dropdownRender to filament Select in spool create page
- Added dropdownRender to vendor Select in filament create page
- Added translation keys for success messages and placeholders
- Pre-fills sensible defaults (diameter 1.75mm, density 1.24 g/cm³)

Closes #1
