fix(console): l1 upgrade builder follow-ups — chain-driven state, bundled predeploys, no snapshots

[anishnar]

Stacked on #4276 (feat/l1-upgrade-json-builder) — final fixes for the L1 upgrade builder so testing can continue on this branch's preview without churning the base PR.

Fixes

Managed/self-hosted detection is server-authoritative

• Select step and builder always query GET /api/console/l1-upgrade/managed (NodeRegistration table); the query-param hint and dashboard match are only in-flight fallbacks.
• mode=detect skips the node-service round-trip on the select step; the GET reports managed: true + serviceError instead of a 5xx when reading the node's file fails.

eth_getActiveRulesAt fallback

• Hosted public RPCs (e.g. Dispatch) don't expose eth_getActiveRulesAt. The RPC route now derives active precompiles from eth_getChainConfig (genesis configs + upgrades.precompileUpgrades replayed up to the latest block) and only surfaces an error when both methods fail. No more error banner on hosted RPCs.

Predeploy presets bundle their bytecode

• The Source Contract dropdown (Transparent Proxy, Proxy Admin, ICM Messenger, Wrapped Native Token, Safe Singleton Factory, Multicall3, Create2 Deployer) fills runtime bytecode from the repo's compiled artifacts — the same ones genesis injects — instead of fetching from an RPC that may not have the contract deployed.
• Presets that need storage initialization get it: proxy (EIP-1967 impl/admin slots), ICM messenger (reentrancy-guard slots), proxy admin (owner ← connected wallet). Manual code edits or custom addresses clear preset storage.

Snapshots removed; the chain itself is the source of truth

• "Save to Builder Hub" / Save Snapshot UI is gone, snapshot route deleted, managed write/restart no longer record snapshots.
• The existing upgrade.json prefills from: managed node file → chainConfig.upgrades over RPC → empty.
• Apply step is strictly either/or: managed L1 → one full-width "Apply Upgrade to N Managed Nodes" button (write + restart in one click); custom/self-hosted docker → only the docker commands with the generated upgrade.json.
• L1UpgradeSnapshot prisma model/migration left in place to avoid migrate drift on the preview DB — can be dropped before merge.

Also carries the earlier round of fixes: structural validation of pasted/imported upgrade.json, Add Wallet prompting the wallet connect flow when disconnected, native minter (and all active allowlist precompiles) getting an "Update Allowlist" path that generates the documented disable + re-enable pair, and the source contract preset dropdown.

Verification

• 197 unit tests pass (tests/unit), including new coverage for deriveActivePrecompiles, extractUpgradeJsonFromChainConfig, storage in stateUpgrades, update-pair generation, and upgrade.json structure validation. tsc --noEmit and eslint clean.
• 31/31 real-browser checks (Playwright + Chrome against next dev): managed/self-hosted/check-failed apply states, snapshot UI removal, base prefill from chainConfig, preset bytecode + storage fill, validation errors, one-click apply through write→restart→success, Add Wallet connect prompt.
• Live-chain scenario against the real Dispatch RPC (no mocks): no eth_getActiveRulesAt banner, Native Minter / Fee Manager / Warp show Active via the chainConfig fallback, and the base upgrade.json prefills with Dispatch's actual feeManagerConfig upgrade.
• Not covered: writes/restarts against the real managed-node service (mocked; needs live managed nodes — that's what this preview deployment is for).
