refactor(bot)!: rename 'ai procurement' -> 'bot/' so the compose build context is committed

The bot service in docker-compose.yml builds from ./bot, but the agent code lived in 'ai procurement/' and ./bot was only a Windows junction on reza.g's machine (and was gitignored) — exactly as the team reported: 'bot/ was never committed — prod-v7's bot is un-buildable from the repo.'

- junction removed; 'ai procurement/' renamed to 'bot/' via git mv (all 41 files keep their history as pure renames)
- 'bot/' dropped from .gitignore (voice/ stays ignored — runtime voice notes; bot/.env stays ignored by bot/.gitignore)
- compose needs no change: context: ./bot and ./bot/app now resolve to committed files
- bot/INTEGRATION-REPORT.md added: full story (problem, root cause, git state, security note on the committed BALE_BOT_TOKEN / AI_API_KEY compose defaults, and usage instructions for the team)

Verified: 41 renames staged with zero secret/cache files; voice/ and bot/.env still ignored.
