Optimize storage usage, key compaction, and TTL tuning across contracts

[devJaja]

Goal: Lower footprints and rents.
Why it matters: Storage is the dominant long-term protocol cost.
Proposed scope:

• Audit all ledger entries for key premises, batch adjacent data, apply short TTLs where semantics allow, enforce entry size caps.
  Acceptance criteria:
• Average entry size reduced and documented.
• TTLs survive realistic audit windows.
