feat: redesign launcher UI and harden runtime controls

[cxymds]

Summary

• redesign the launcher UI with a cleaner control panel and refreshed log area
• lock all configuration inputs while the service is running and improve runtime state sync
• add console port configuration, stricter port validation, and safer log/config handling

Changes

• rebuilt the left-side control surface, summary cards, and log panel styling for a simpler cross-platform layout
• prevent editing data path, host, API port, console settings, and credentials while RustFS is running
• add managed-process status checks so the UI distinguishes launcher-managed processes from externally running services
• add console port support end-to-end, including persistence, form input, process arguments, and port-conflict validation
• restore explicit default values for access key, secret key, and console port in the form
• stop persisting credentials to local storage, redact secrets from logs, and avoid logging raw command-line credentials
• switch frontend log rendering to stable IDs so repeated log lines render correctly
• keep log scrolling inside the right-side panel and hide the left-panel scrollbar while preserving scroll behavior

Validation

• cargo fmt --all --check
• cargo check --workspace
• cargo clippy --workspace --all-targets -- -D warnings
• cargo test --workspace

Notes

• cargo test --workspace currently passes with 0 tests in this repository
• manually verified that omitting access/secret key still starts RustFS with its current default credentials
