feat: migrate sponsor + distribution routes to getConfig()

- sponsor-outreach: cooldownDays, maxOutreachPerRun, rateCardTiers from sponsor_config
- gemini-outreach: geminiModel from pipeline_config, renamed RATE_CARD to DEFAULT_RATE_CARD
- resend-notify: accept optional fromEmail + notificationEmails params (backward compatible)

Keeps all API keys and auth secrets as process.env.
