Add structured logging to IntranetController actions

Extensive structured logging was added throughout IntranetController and all invoice/account handlers to improve traceability and debugging. Logging now covers action entry/exit, error conditions, and key parameters (user IDs, invoice IDs, etc.). Handlers log warnings for missing/invalid input and info/debug for significant events. Minor refactoring extracts form values for better logging. The jQuery `rwText` plugin was hardened against null input. Updated minified JS, font assets, and OCORE submodule. No functional changes to `tools.js`.
