Summary

Upgrade PCEToken (UUPS proxy) and PCECommunityToken (Beacon) on Polygon to v16:

• PIP-16 — Owner-controlled token value operations (supersedes PIP-12). Replaces the PIP-12 treasury/role-manager model with simpler owner-only increaseTokenValue / splitToken, moves TokenValueIncreased / TokenSplit event emission to PCEToken, and renames the now-unused treasuryWallet / _roles storage slots to __deprecated_* for layout compatibility. (#40)
• PIP-13 fix — Re-emit MetaTransactionFeeCollected alongside MetaTransactionFeeSwapped so existing indexers tracking per-payer fee burden continue to work after PIP-13's fee auto-swap landed in v15. (#42)
• PIP-15 revert — Remove the message-count parameter transfer/auth functions and their EIP-712 typehashes; PIP-15 is being put on hold pending further design review. (#43)
