feat: migrate sponsor + distribution routes to getConfig()

- sponsor-outreach: cooldownDays, maxOutreachPerRun from sponsor_config
- gemini-outreach: geminiModel from pipeline_config, rate card from caller
- sanity-distribute: pass distribution config to notifySubscribers
- resend-notify: accept fromEmail + notificationEmails params
