feat(ai-bot): make bot account email configurable via env var

[dnplkndll]

Summary

Makes the AI bot account email configurable via AI_BOT_EMAIL env var instead of hardcoded to huly.ai.bot@hc.engineering.

Resolves hcengineering/huly-selfhost#239

Motivation

Self-hosted deployments send email notifications to the hardcoded huly.ai.bot@hc.engineering when the bot is mentioned offline — an unreachable address for self-hosters.

Design

• setAiBotAccountEmail() / getAiBotAccountEmail() on the shared @hcengineering/ai-bot plugin — mutable at startup, defaults to original email
• getAiBotEmailSocialKey() — derives social key from the configured email at call time
• Original aiBotAccountEmail and aiBotEmailSocialKey constants kept (used by client-side code that doesn't have env vars)
• Client plugin unchanged — queries by the default constant, which still works because the bot retains its original social identity after re-registration

Env vars

Service	Var	Default	Required
ai-bot	AI_BOT_EMAIL	huly.ai.bot@hc.engineering	No
transactor	AI_BOT_EMAIL	huly.ai.bot@hc.engineering	No

Both services must use the same value if set.

Changes (12 files)

File	Change
plugins/ai-bot/src/index.ts	Add get/setAiBotAccountEmail(), getAiBotEmailSocialKey()
services/ai-bot/pod-ai-bot/src/config.ts	Add Email from AI_BOT_EMAIL env (imports default from plugin)
services/ai-bot/pod-ai-bot/src/start.ts	Call setAiBotAccountEmail(config.Email) on startup
services/ai-bot/pod-ai-bot/src/utils/account.ts	Use getter functions
services/ai-bot/pod-ai-bot/src/utils/platform.ts	Use getter functions
pods/server/src/__start.ts	Read AI_BOT_EMAIL, call setAiBotAccountEmail()
foundations/server/packages/middleware/src/identity.ts	Import from @hcengineering/ai-bot (was duplicate hardcoded string)
foundations/server/packages/middleware/src/pluginConfig.ts	Use getter function
server-plugins/ai-bot-resources/src/index.ts	Use getter function
**/package.json + pnpm-lock.yaml	Add @hcengineering/ai-bot dependency

Not changed: plugins/ai-bot-resources/src/utils.ts (client-side, correctly uses constant), models/contact/src/migration.ts and dev/tool/src/db.ts (hardcoded strings reference historical data).

Testing

Deployed to Hetzner K8s cluster with AI_BOT_EMAIL=aibot@ledoweb.com:

• ai-bot: 0 restarts, registers email:aibot@ledoweb.com as new social identity
• Original email:huly.ai.bot@hc.engineering identity preserved (backwards compat)
• DM with Huly AI bot works — bot receives and responds to messages
• Default behavior (no env var) unchanged
