ido: port "CldIdo00" signature + announcement permanentLiquidityMinFee

Browse source 
Sync the IDO indexer to libriften 48aa1f7 (+ follow-ups):

- IDO_SIGNATURE 20->10 bytes: [0x08 "CldIdo00" 0x75] (was OP_PUSH18
  "CauldronIdo-2026Q2"). The separate "CauldronIdo0" announcement
  signature is folded into the same 8 raw bytes, so
  IDO_PREINIT_ANNOUNCEMENT_SIGNATURE = 6a 4c b9 + "CldIdo00";
  is_preinit_broadcast is now length-agnostic. Electrum mempool
  filters track automatically (they reference the constants).
- Recompile the 3 affected contracts from templates: IDO initiator
  233->231, IDO preinit 1469->1465, offering launcher 630->628.
  IDO_POSTLAUNCH_CONTRACT and the other offering contracts are
  byte-identical and left as-is.
- Announcement OP_RETURN carries permanentLiquidityMinFee as a 2-byte
  field at data[166..168]; mainData is now 185 bytes. Read minFee from
  the announcement rather than the (unreadable) postlaunch copy.

Fix the source of the two "free" postlaunch params:

- Output #7 (ido initiator bytecode storage) is P2SH32, so the partial
  bytecode cannot be read back from it. Drop the impossible extraction
  (extract_params_from_partial_ido_initiator_bytecode +
  PartialPostlaunchExtractedParams). extract_data_from_storage_script_
  with_data_and_size is kept for its valid callers (revealed redeem
  scripts, bare bcmr storages).
- orbPoolParamsCategory now comes from the ORB IdoParams NFT commitment
  (output #10). The commitment parse is moved above the params
  construction so the value is available; the now-tautological
  orbPoolParamsCategory vs NFT check is removed.
- Verification is the existing output #7 rebuild: build the expected
  bytecode from the announcement values plus the NFT-sourced
  orbPoolParamsCategory, hash to P2SH32, and compare. Since minFee is a
  2-byte announcement field it always fits the postlaunch's 2-byte push,
  so build_partial_postlaunch_bytecode stays infallible.

- Tests: preinit_detect -> legacy_preinit_announcement_not_detected
  (legacy fixture must no longer be detected under the new signature);
  replace the extraction round-trip test with a structural check of the
  partial postlaunch bytecode layout.
