style(journals): standardize Skeleton v4 preset-* classes across all journal components

- Replace all Skeleton v2 variant-* classes with v4 preset-* equivalents
  - variant-filled-* → preset-filled-*
  - variant-soft-* / variant-ghost-* → preset-tonal-*
  - variant-outline-* → preset-outlined-*
  - variant-form-material removed from inputs/selects/textareas
  - input-bordered removed

- Fix dark mode: journal entry content hover (dark:hover:bg-blue-950)
- Fix dark mode: journal obj view section/description bg and text colors
- Fix modal headers: add dismissable=false + explicit X close button (all 3 journals modals)
- Fix DaisyUI wrappers removed from modal_journal_entry_append
- app.css: add global select padding-inline to fix text-against-border issue
