Add Tron chain to Pezkuwi overlay; regenerate merged configs

- pezkuwi-overlay/chains/pezkuwi-chains.json: add Tron mainnet
  (native TRX + USDT-TRC20) chain entry, plus new TRX/Tron icons
  under pezkuwi-overlay/icons/ (the correct source location - synced
  into the top-level icons/ output by sync_from_nova.py).
- Regenerate all chains/*, xcm/*, staking/* merged output via
  sync_from_nova.py against the current nova-base submodule state.
- Also picks up previously-uncommitted local fixes: canonical
  Telegram/Twitter links (t.me/kurdishmedya, x.com/bizinikiwi) in
  README/docs/banners, and Pezkuwi mainnet + People chain SubQuery
  staking overrides.
