feat: switch theme from dracula to monokai (custom)

Replace dracula with a custom monokai theme (from dachinat/daisyui-themes,
with modifications: all -content colors set to black, base-300 changed
to #3b3a3a). Dracula is unloaded; monokai is the sole bundled theme and
default.

Also adds .env.development (dev ports 24203/24205) and .env.production
(arch ports 24991/24990) so Vite uses the correct backend per mode.
Excludes src/themes/ from biome (third-party CSS).

683 tests green.
