fix(quotas): tighten Team/Enterprise daily preview caps to stay profitable

The earlier caps (Team 150/day, Enterprise 1000/day) used Sonnet/Opus pricing
that put max-usage above the tier's monthly revenue — a Bot with a Team
subscription could out-cost €199 in Anthropic spend. Drop to 50/day Team
and 200/day Enterprise; both now keep ~55-65% margin even when maxed.

Pricing page Team feature line updated to match (150 -> 50). Build caps
loosened slightly less since the 24h cache TTL makes most builds cache-hits.
