Aditya Tripathi 623bf89543 fix(railpack): interpolate build-time env variables by sourcing build-time .env
Railpack builds forwarded build-time variables inline as `env 'KEY=VALUE'`,
which single-quotes each value and prevents shell interpolation. References
like BETTER_AUTH_URL=$COOLIFY_URL reached the build as the literal string
"$COOLIFY_URL" instead of the resolved URL, breaking builds that validate
their env (e.g. SvelteKit/better-auth).

Wrap the railpack `docker buildx build` invocation with the same
wrap_build_command_with_env_export() helper used by the Dockerfile and
Nixpacks build paths, sourcing the build-time .env file (which writes
COOLIFY_* first and double-quotes normal vars to allow $VAR expansion).
Only buildpack control variables (NIXPACKS_/RAILPACK_), excluded from that
file and never needing interpolation, remain inline. Secret flags are
unchanged and read the interpolated values from the exported environment.

Fixes #10736
