fix(abi): ship the Ricardian clauses, and write the eight that were missing

[robrigo]

Not for v2.0.0. This changes the ABI, so it changes abiSha256, and the v2.0.0 release plus the four live msig proposals are pinned by that hash. It targets a later release.

The contract ships no Ricardian text at all

resource/atomicassets.contracts.md is 27 KB of Ricardian clauses, correctly named and correctly placed, that CDT never embeds. The published atomicassets.abi has ricardian_clauses: [] and every one of its 47 actions carries ricardian_contract: "".

The cause is a missing flag, and the sibling repository proves it:

atomicmarket  cdt-cpp -abigen -contract=atomicmarket -I./include -R./resource ...   -> 51 actions carry Ricardian text
atomicassets  cdt-cpp -abigen -contract=atomicassets -I./include ...                -> 0

The consequence is user-facing: a wallet asking someone to sign an AtomicAssets transfer or burnasset has no human-readable description to show them. AtomicMarket shows one. This is the document that tells a signer what they are agreeing to.

Eight clauses were also missing

Turning the flag on alone would have shipped a partial Ricardian, which is worse than an obvious absence: some actions would carry a description and others silently would not.

Of the 47 actions, 9 are log* actions guarded by require_auth(get_self()). They are dispatched inline by the contract, never signed by a user, so they need no clause and no wallet ever renders one. That leaves 38 user-signed actions, of which 8 had none, all introduced by v2:

createtempl2, settempldata, deltemplate, redtemplmax, setschematyp, createauswap, acceptauswap, rejectauswap

They are written here in the file's existing house style, using the same spec_version, icon, description and clauses structure, and the same handlebars conventions as neighbouring clauses ({{#if}} blocks for the transferable, burnable and max_supply variants in createtempl2, mirroring createtempl).

Coverage after this change: 38 of 38 user-signed actions have a clause, 0 missing.

Wording that deserves review

Each clause states what a signer is agreeing to, and several carry real consequence that I have tried to make explicit rather than neutral:

• acceptauswap says plainly that accepting transfers control of the collection, including the right to authorize accounts and set the market fee.
• settempldata notes that already-minted assets are affected, because mutable data is read from the template rather than copied onto each asset.
• setschematyp notes that descriptors are replaced in full, so an omitted descriptor is removed.
• deltemplate and redtemplmax state that the effect is permanent.

These are legally-shaped text. I would want whoever owns product or legal wording to read them before they ship, rather than treating my drafting as final.

Verification

ricardian_clauses stays empty after this, which is expected: that array is populated from a <contract>.clauses.md file, which this repository does not have and which atomicmarket does not have either. The per-action ricardian_contract field is what wallets render, and that is what the -R flag populates.

Worth adding a CI assertion that the built ABI carries non-empty ricardian_contract for every non-log action, so this cannot silently regress again. Not included here to keep the change reviewable.
