[S3-E.1] aptos: REST chain template fixed + L1-CLI gate bug fix

S3-E wave-E, chain 1/5 (aptos).

Changes:
1. config/chains/aptos.json
   - rpc_methods.single: 'GET /v1' (collection root, no address)
     -> 'GET /v1/accounts/{addr}' (account info with address)
   - Added _meta.rest_paths: maps 5 logical method keys to
     {method, path} dicts. RestAdapter._resolve_path requires this
     map; without it cli.py raises ValueError 'method X not in
     _meta.rest_paths. Available: []'. Path templates use {address}
     placeholder (RestAdapter only substitutes {address}).
   - Added _meta.health_probe: GET /v1 + parse_jq '.block_height'
     (Aptos response includes x-aptos-* headers but body also has
     block_height, so the same endpoint serves both health probe
     and bench traffic shape verification).

2. tests/test_chain_adapters.py (L1-CLI gate fix)
   - Bug: test_cli_build_target_all_36_chains did
     base64.b64decode(tgt["body"]) which KeyError'd on GET targets
     (vegeta JSON omits "body" field for GET). aptos triggered this
     after S3-E.1 fix because it's the first chain to produce GET
     targets through the new path. Fix: tgt.get("body", "") with
     empty-string fallback.
   - Without this fix the invariant would silently mis-classify
     every healthy GET-only chain as broken, defeating the entire
     monotonic-shrink guarantee.

3. tests/test_chain_adapters.py (KNOWN_BROKEN_CLI ledger)
   - Removed 'aptos' entry (chain is now healthy via cli.py).
   - len() assertion: 16 -> 15 (1 chain fixed in S3-E.1).

Verification:
- L1 (unit + adapter contract): 10/10 PASS (was 10/10, no regression)
- L1-CLI gate: healthy 20/36 -> 21/36, broken 16/36 -> 15/36
- L2 (cli.py batch mode): 4/4 aptos targets generated, all addresses
  correctly substituted into URL path
- L3 (real production pipeline target_generator.sh):
  exit=0, "Successfully generated 4 test targets"
  Output file format:
    {"method":"GET","url":"http://.../v1/accounts/0x1","header":{}}
    {"method":"GET","url":"http://.../v1/accounts/0x2","header":{}}
    ... (4 vegeta-compatible targets)

Wave S3-E progress: 1/5 chains (aptos done; algorand/hedera/tezos/ton pending)
KNOWN_BROKEN_CLI invariant working as designed — caught the GET body
KeyError immediately on first fix attempt.
