Recalibrate estimate for SMB acceptability

Real-world feedback: list-rate calc overshot SMB-acceptable levels.
- scaling: driver properties_total -> subbrands_total (chains share templates),
  cap x6.5 -> x2.0, applied to On-page only (Technical now fixed site-wide)
- add 'smb' entry tier (lean hours @ 0.55 billing); 3-tier auto-select
  (smb/basic/treatment) by portfolio size; per-tier billing; --baseline smb enabled
- docs (findings_to_service.md, SKILL.md) synced to 3-tier model

Effect: SHR 25-property chain 71.5M -> 29.5M; SMB single hotel ~3.0M;
basic/treatment still reproduce real 10.5M/25.0M at 1 property.
