feat: lots 430-434 — /upscale, /count, /speak, emoji health, /flip

Lot 430: /upscale placeholder (needs ESRGAN model)
Lot 431: /count — file counts for all data directories
Lot 432: /speak <persona> <text> — force TTS as any persona
Lot 433: Emoji health indicators in admin dashboard
Lot 434: /flip enhanced (PILE/FACE + emoji)

132 commands, 211 tests.
