feat: link QTC bridge deposits and withdrawals across both chains
#44 part 3. A deposit is linked exactly: the NEAR mint is bridge-mng.near calling omft.near.ft_deposit, whose arguments carry the Intents account and BRIDGED_FROM's txHash — Blake2-256 of the depositor's Quantus transfer into their deposit address, length prefix included (checked: extrinsic 1 of block 180,029 hashes to 0xc4444afc…, the hash in mint piPTXyoq…). `chain_extrinsic.hash` is stored from now on and filled for the bridge's deposit transfers. `bridgescan` reads mints from gargravarr (bridge-mng.near is on shard 8), each confirmed executed before it is recorded. History before our nodes is found by bisecting the token's supply — 16 changes before gargravarr's oldest block, 204 archive calls — and a rise is accepted as mints only when the mints around it sum to it exactly. Withdrawals (ft_withdraw with WITHDRAW_TO) come from the intents scan, rewound to frankie's oldest block (migration 0018); custody's payout is matched by a strict, stated rule, as an inference, with the fee it implies — every pre-node withdrawal paid exactly 0.002 QTC less. `/bridge/deposits` and `/bridge/withdrawals`; a linked-transactions panel on the NEAR Intents page.
