fix(config): preserve preloaded rxconfig classes

[FarhanAliRaza]

Summary

• Reuse the current project's already-imported rxconfig configuration instead of re-executing it during app initialization.
• Remove the redundant reflex run config reload after port and host overrides are already persisted.
• Isolate app/config unit-test context state and cover direct rxconfig classes, pickle identity, and cross-project loading.

Validation

• 327 focused unit tests passed.
• Ruff and pyright passed.
• A real Reflex app passed production export, dev startup, State events, pickle roundtrip, and an rxconfig.py hot reload.

Confidence Score: 4/5

The behavioral fix appears safe, but the explicit repository requirement against hardcoded identifier literals must still be satisfied before merging.

Summary

The PR preserves classes defined in a preloaded rxconfig.py by reusing the active registration context’s configuration rather than re-executing the module. It also routes backend servers through a config-first app factory and removes a redundant CLI reload.

• Reuses cached configuration during App construction and backend app loading.
• Preserves class and app identity in forked workers with regression coverage.
• Isolates app and config slots between unit tests.
• Removes the redundant run-command configuration reload.
