test(e2e): consolidate automine token suites

[spalladino]

Part of the e2e round-2 consolidation (PR 1 of 9). Merges the automine token/ suites into fewer, parameterized files, with no loss of asserted behavior. Failure cases are written as explicit per-case tests (no shared dispatch DSL), and the two token harnesses share member names so the merged suites can reuse code.

Merges (old files → new)

• Transfer quintet → two files. transfer.test.ts (happy paths + the private Transfer event assertion, grouped by entrypoint) and new transfer_failures.test.ts (explicit per-case failure tests, grouped by entrypoint). Deletes transfer_in_private, transfer_in_public, transfer_to_private, transfer_to_public.
• burn.test.ts + blacklist_burn.test.ts → burn.test.ts via describe.each over the two harnesses. Each scenario's setup returns its harness directly; only the differing private-burn method (burn_private vs burn) is mapped per scenario (burn_public is identical on both). The blacklist-only "sender is blacklisted" cases are an extra block. Deletes blacklist_burn.test.ts.
• blacklist_transfer_private.test.ts + blacklist_transfer_public.test.ts → blacklist_transfer.test.ts, parameterized by authwit mechanism (private-proxy vs public) over a single shared harness (private transfers only touch private balances, public only public, so neither disturbs the other's mint). Failure cases are explicit per-case tests inside the mechanism loop. Deletes both.
• minting.test.ts → describe.each(['Public','Private']) for the mirrored role/overflow cases; the private-only ABI-encoding overflow case stays explicit.
• reading_constants.parallel.test.ts → reading_constants.test.ts: dropped the .parallel suffix, converted the 6 its to a single it.each, and deleted the empty no-op beforeEach.

Shared helpers (token_test_helpers.ts)

• balanceOf / halfBalanceOf / amountAboveBalance — the "read balance, take half or balance±1, assert > 0" idiom.
• assertPublicAuthwitReplayRejected / assertAuthwitProxyReplayRejected — the grant/consume-then-replay dances for public and private-proxy authwits.
• deployAmmWithTokens — the AMM + 3-token + authwit-minter deployment boilerplate previously duplicated in token/amm.test.ts and simulation/kernelless_simulation.test.ts; both now call it.

Adopted the balance helpers (and the proxy-replay helper in unshielding) in blacklist_shielding.test.ts and blacklist_unshielding.test.ts.

Harness name unification

TokenContractTest and BlacklistTokenContractTest now share member names so the merged burn suite reads members off the harness directly:

• Both expose a public applyMint() called after setup(); the Token harness's pre-setup applyMintSnapshot() flag is gone.
• The Token harness's secondary account is renamed account1Address → otherAddress to match the blacklist harness's owner/other vocabulary. Consumers updated accordingly (transfer, minting, access_control.parallel, private_transfer_recursion.parallel).

Quick wins

• Deleted the byte-identical duplicate it('transfer on behalf of other, wrong designated caller') in the old transfer_in_public.
• Collapsed the triplicate it.skip('transfer into account to overflow') (GH Cheatcodes tracking issue #1259) to a single copy in transfer_failures.test.ts.
• Resolved the new TokenContractTest('transfer_private') harness-name collision (the two files that shared it were merged; the survivors use distinct names).
• Removed the redundant inline tokenSim.check() calls from the old transfer_to_private (the harness afterEach already checks).

Preserved-assertion mapping (summary)

Every asserted behavior survives: each failure mode × entrypoint pair is an explicit test; happy paths and event/balance/simulator assertions stay explicit. The CHECK_ALERTS/Grafana publishing_mana_per_second QoS guard from the old transfer_in_public moved to transfer.test.ts (which now owns the public-transfer execution).

Intentional changes (no assertion lost)

• Balance-unchanged checks: where an original asserted only the owner's balance unchanged (private wrong-caller cases), the failure tests now assert both the owner's and other's balances unchanged — a strengthening, since simulate cannot move balances.
• Dropped one redundant createAuthWit+authWitnesses in the old transfer_in_public over-balance-via-authwit case: the public authwit alone is the authorization mechanism (the private witness was inert on a public call); the U128-underflow revert + balances-unchanged assertions are unchanged.
• For transfer_to_public over-balance / invalid-nonce, the recipient is now other rather than self; the asserted error (Balance too low / invalid nonce) is independent of the recipient.
