refactor: unified ingest pipeline + modular Redfish profile framework

Implement the full architectural plan: unified ingest.Service entry point
for archive and Redfish payloads, modular redfishprofile package with
composable profiles (generic, ami-family, msi, supermicro, dell,
hgx-topology), score-based profile matching with fallback expansion mode,
and profile-driven acquisition/analysis plans.

Vendor-specific logic moved out of common executors and into profile hooks.
GPU chassis lookup strategies and known storage recovery collections
(IntelVROC/HA-RAID/MRVL) now live in ResolvedAnalysisPlan, populated by
profiles at analysis time. Replay helpers read from the plan; no hardcoded
path lists remain in generic code.

Also splits redfish_replay.go into domain modules (gpu, storage, inventory,
fru, profiles) and adds full fixture/matcher/directive test coverage
including Dell, AMI, unknown-vendor fallback, and deterministic ordering.
