TTS fixes, Inworld improvements, footer redesign, episodes 15-25, invoice script fix

- Fix TTS text pipeline: new caps handling (spell out unknown acronyms, lowercase
  emphasis words), action-word lookahead for parenthetical stripping, abbreviation
  expansions (US→United States, NM→New Mexico), pronunciation fixes
- Inworld TTS: camelCase API fields, speakingRate per-voice overrides, retry logic
  with exponential backoff (3 attempts)
- Footer redesign: SVG icons for social/podcast links across all pages
- Stats page: show "Rate us on Spotify" instead of "not public" placeholder
- New voices, expanded caller prompts and problem scenarios
- Social posting via Postiz, YouTube upload in publish pipeline
- Episode transcripts 15-25, terms page, sitemap updates
- Fix invoice script: match Timing totals using merged Task+App intervals
