All MITIGATION_ABILITIES entries now carry a statusId field (FFLogs status ID =
XIVAPI row_id + 1,000,000). The mitigIdMap is seeded from these static IDs as
fallback for abilities absent from masterData (e.g. pre-pull shields). Removes
the need for separate applybuff/removebuff API calls for name resolution. Also
adds shield buffType with tooltip on absorbed value, expanded icon set, and
unmitigatedAmount/mitigated passthrough.
