Raise Daily Cap

Raise a conglomerate's daily credit cap — the internal platform's only write.

The decision is core.billing.resolve_support_daily_cap — the same function margot_actions.raise_daily_cap calls, not a copy of it, so the two surfaces cannot drift: raise-only (never lowers), never re-imposes a finite cap on an unlimited (0) conglomerate, clamped to SUPPORT_DAILY_CAP_CEILING, and a non-finite ask (NaN/±inf, which would defeat every comparison and land an uncapped row) resolves to no change. Worst case for a compromised internal service is therefore nudging a 24h rate limit up to the ceiling — real spend stays bounded by the credit balance.

clamped flags an ask above the ceiling so the caller can offer a human. changed reflects the value actually persisted, so it is False for every no-op. Unknown conglomerate → 404.
