zeekay 705e38c45e fix(indexer): gate V2/V3 AMM handlers to canonical factory; floor parseLimit everywhere
Red re-verify found the V4 AMM-spoof gate left a parallel bypass.

MEDIUM — V2/V3 AMM handlers were UNGATED: handlePairCreated, handlePoolCreated,
handleSwapV2, handleSwapV3 accepted events from ANY emitter — a parallel path to
seed phantom pairs/pools/swaps and inflate the SAME public Factory/TVL/volume
aggregates the now-gated V4 handlers (0x9999) block. Mirror the V4 gate:
  - PairCreated/PoolCreated now require the canonical FactoryV2/FactoryV3 emitter
    (the AMM trust root), exactly as V4 requires 0x9999.
  - V2/V3 Swaps are emitted by the pair/pool, not the factory, so the gate is
    "is the emitter a pool the canonical factory created?" (isKnownPool). The
    factory authorizes a pool; only that pool's Swaps are honored. A rogue
    factory's PairCreated is rejected, so its pools are never registered, so its
    Swaps are rejected — the whole parallel path is closed.
  - Pair/pool keys lower-cased at seed so the Swap-side lookup is RPC-casing safe.
  - Factory addresses configurable (Config.FactoryV2/V3 + FACTORY_V2/V3 env),
    default to canonical Lux mainnet (LuxMainnet.Factory{V2,V3}); main wires env.

INFO — the per-namespace resolver limit lacked the `if limit < 1 { limit = 100 }`
floor that resolvers/dex has, so a negative/zero `first` flowed to ListByType
(`first:-1` = "no limit" in SQLite — an unbounded scan). Brought every pl()/
parseLimit() copy to the dex-canonical body (floor <1->100 + cap 1000); fhe and
platform also gained the previously-missing 1000 cap. All namespaces now identical.

Tests (go test ./...): indexer + resolvers/{dex,exchange,fhe,platform} green.
  - TestHandleV2_RejectsNonFactory, TestHandleV3_RejectsNonFactory: rogue
    PairCreated/PoolCreated/Swap seeds nothing and does not inflate the factory
    aggregate; the canonical-source event IS honored end-to-end.
  - TestPL_ClampsFirst / TestParseLimit_ClampsFirst (exchange/fhe/platform):
    negative/zero floored to 100, capped at 1000.
