chore: fix build dependencies and frontend config

Migrate Docker SDK from github.com/docker/docker (+incompatible)
to github.com/moby/moby/client v0.3.0 + moby/moby/api v1.54.0
(proper Go modules). Adapt all container/image/network operations
to the new moby API (Filters, ContainerListOptions, PullResponse,
InspectResult, etc.). Add AsyncTriggerDeploy runDeploy method.

Fix SvelteKit build: disable prerender, set strict=false for SPA,
bump vite-plugin-svelte to v5 for vite 6 compat.

Add .dockerignore to exclude .git, node_modules, plans.
