fix(ux): optimize event lists and fix editor line wrapping

- Implemented 'Details' toggle in Session lists to defer expensive presenter/file sub-component renders, improving initial hydration speed.
- Fixed line-wrapping for long lines in Journals Editor (both plain textarea and CodeMirror).
- Updated TODO.md and GEMINI.md to reflect Journals standardization and performance optimizations.
