fix: basic-token tutorial — match actual evo-sdk API

[thepastaclaw]

Adds a corrected version of the Basic Token tutorial that compiles against @dashevo/evo-sdk@3.1.0-dev.1.

Changes from original tutorial

API	Tutorial (broken)	Fixed
contracts.publish()	{ identityId, documentSchemas, tokens: [config] }	{ dataContract: new DataContract({..., tokens: {0: tokenConfig}}), identityKey, signer }
Token config	{ conventions, manualMinting: { rules: { type: "ownerOnly" } } }	Full TokenConfiguration with ChangeControlRules, TokenDistributionRules, TokenKeepsHistoryRules, TokenMarketplaceRules
tokens.mint()	{ tokenId, amount: number, privateKeyWif }	{ dataContractId, tokenPosition: 0, amount: bigint, identityKey, signer }
tokens.transfer()	{ tokenId, identityId, privateKeyWif }	{ dataContractId, tokenPosition, senderId, identityKey, signer }
tokens.burn()	{ tokenId, identityId, privateKeyWif }	{ dataContractId, tokenPosition, identityId, identityKey, signer }
Balance lookup	balances.get(tokenId) (string)	Iterate Map<Identifier, bigint> entries
contract.getId()	method	contract.id (property)

npx tsc --noEmit passes with zero errors.

✅ Live Testnet Run — All Steps Passed

Ran the basic token tutorial on testnet with identity HHjmkbcwqFzToaoyvQcP45JZro7PoczAv7Nii57uYPX1.

Contract published: EiVuRbU3d9ANGjnNokBJamMDGaL9QdPBsV44fUeMPMNy
Token ID: AmyDrLavqJcPLgU7K6NxCLom7JJKi96q5fZMMuxtBRkF

Minting 10,000.00 CoffeeCoins...
Minted!
Balance: 10000 CoffeeCoins

Burning 100.00...
Burned!
After burn: 9900 CoffeeCoins

=== BASIC TOKEN: ALL STEPS PASSED ===

Additional issues discovered during live testing

1. Token operations require CRITICAL security level key — The tutorial uses signingKeyIndex: 0 (Master key) for token ops, but minting/burning/transferring tokens requires a CRITICAL-level key. Using HIGH or MASTER fails with "Invalid public key security level HIGH. The state transition requires one of CRITICAL".
2. Schema properties require position fields (same as car-sales).
3. identityNonce needs +1 (same as car-sales).
4. TokenConfiguration is extremely verbose — What the tutorial shows as 10 lines of config requires ~30 lines of SDK class instantiation with ChangeControlRules, TokenDistributionRules, TokenKeepsHistoryRules, and TokenMarketplaceRules. This is the biggest usability gap.
