Integrate TDS v1.2 lt.* APIs throughout app
- app.js: replace raw fetch/escHtml/fmtRelTime with lt.api, lt.escHtml, lt.time.ago; modal open/close via lt.modal; add _toIso() for timestamp normalisation
- index.html: data-action="refresh", data-duration pills, lt.autoRefresh.start, remove local fmtRelTime
- suppressions.html: lt.api.post/delete, data-dur pill delegation
- base.html: user avatar with initials, admin badge, lt.keys.on('r') replaces manual keydown handler
- base.css: add dot-*, chip, row-state aliases so apps can use unprefixed class names
