fix(dashboardAPI): resolve InfluxDB datasource uid at push time

Templates baked in a hardcoded influxdb datasource uid that only matched the
Grafana the templates were authored against. Any other Grafana (fresh laptop,
VPS, rebuilt instance) rendered every panel as "Datasource <uid> not found".

resolveDatasourceUid() queries GET /api/datasources, picks the first influxdb
one, and caches the result. rewriteDatasourceUid() then walks panels, nested
row panels, panel.targets[], and templating.list[] and rewrites every influxdb
uid before the dashboard is pushed. Annotation datasources (type: "grafana")
and template-variable refs ($datasource) are left alone. Failure is silent and
panels keep the template uid, so behavior is never worse than before.

+# dashboardAPI output manifest
+
+Per `.claude/rules/output-coverage.md`: every output on every layer, in every state.
+
+## Port 0 (process — Grafana upsert messages)
+
+Emitted by the command handler(s) after a `child.register` or `regenerate-dashboard` message. Shape is the same for both; `meta.trigger` distinguishes them.
+
+| Key | Source method | Type | States tested | Test file |

+
+**Degraded-state convention:** missing keys are **absent**, never set to `null`. The `http request` consumer treats absent headers/payload fields as defaults.
+
+## Port 1 (InfluxDB telemetry)
+
+dashboardAPI emits **nothing** on Port 1 by design — it has no measurements, no tick loop, no telemetry. Verified by absence: no `formatForInflux` import, no Port 1 wires in `examples/`.
+
+## Port 2 (registration / control plumbing)
+
+dashboardAPI is a **sink** for `child.register` messages, not a source — it does not register itself with any parent. Nothing emitted on Port 2.
+
+## Structured log outputs
+
+| Event | Level | Triggered by | Fields | Test |
+|---|---|---|---|---|
+| `regen-emitted` | info | successful composition (auto or manual) | `event`, `trigger`, `dashboardApiId`, `childId`, `dashboardCount` | `test/basic/slice43-output-manifest.basic.test.js` |
+| `regen-skipped` | info | diff predicate says subtree unchanged | `event`, `outcome: 'no-diff'`, `trigger: 'child.register'`, `dashboardApiId`, `childId`, `subtreeSize` | `test/basic/slice43-output-manifest.basic.test.js` |
+| `manual-regen-requested` | info | `regenerate-dashboard` topic received | `event`, `trigger: 'manual'`, `dashboardApiId`, `cachedChildCount` | `test/basic/slice41-manual-regen.basic.test.js` |
+| `parent-panels-deduped` | debug | no-data-duplication filter removed root panels | `event`, `before`, `after`, `rootTitle` | _covered by composition tests in slice39_ |
+| `flows:started` | debug | Node-RED runtime emits flows:started | `event: 'flows:started'`, `type`, `diff` (count summary) | _covered by predicate tests in slice36_ |
+
+## specificClass return shapes
+
+| Method | Return shape | Populated states | Degraded states | Test |
+|---|---|---|---|---|
+| `buildDashboard(opts)` | `{ dashboard, uid, title, softwareType, nodeId, measurementName, bucket }` or `null`; `measurementName` mirrors `outputUtils.formatMsg` (`general.name` \|\| `<softwareType>_<id>`) so the dashboard `_measurement` var matches the telemetry series; `bucket` is the resolved Influx bucket | success (name set + name empty/fallback) | `null` when no template for softwareType | `test/basic/slice43-output-manifest.basic.test.js`, `test/basic/slice46-measurement-name-parity.basic.test.js` |
+| `generateDashboardsForGraph(root)` | flat pre-order array of `buildDashboard` results (root first, then full descendant subtree); per-parent dedup + links applied at every level; machineGroup roots additionally get per-pump fan-out panels injected (see below) | 0..N children, 3-level tree, diamond, cycle | empty array when root config missing | `test/basic/slice35-graph-perf-and-uid-uniqueness.basic.test.js`, `test/basic/slice44-recursive-discovery.basic.test.js` |
+| `_injectMachineGroupPumpPanels(parentDash, children)` | mutates an MGC dashboard in place: replaces the static Total Flow/Power panels with 3 timeseries panels (Pump % Control, Pump Predicted Flow vs Demand, Pump Predicted Power) whose queries are generated from the child-pump measurement names. Panels carry `meta.emittedFields: []` so they survive the dedup pass | MGC with ≥1 rotatingMachine child | no-op for non-MGC dashboards or MGC with zero pump children (static totals retained) | `test/basic/slice47-mgc-pump-panels.basic.test.js` |
+| `subtreeChanged(diff, ids)` | boolean | id-in-diff, no-id-in-diff | null diff → true (cold start) | `test/basic/slice36-diff-predicate.basic.test.js` |
+| `subtreeIdsFor(myId, child)` | Set\<string\> | myId + every id in the child's full subtree (recurses all levels, cycle-safe) | myId only when child has no children | `test/basic/slice36-diff-predicate.basic.test.js`, `test/basic/slice44-recursive-discovery.basic.test.js` |
+| `collectEmittedFields(dashboard)` | Set\<string\> | populated dashboard | empty set for `null`/`{}`/`{panels:[]}` | `test/basic/slice37-emitted-fields.basic.test.js` |
+| `cachedChildSources()` | array of child sources | 0..N cached | empty after construction | `test/basic/slice41-manual-regen.basic.test.js` |
+
+## Anti-patterns enforced
+
+- ❌ Emitting `{payload: null}` — `handlers.emitDashboardsFor` always builds `payload: { dashboard, overwrite, ... }`. Verified.
+- ❌ Mixing absent vs null for optional fields — `folderUid` / `folderId` are **absent** when unconfigured, never `null`. Verified.
+- ❌ Per-call token stamping — token is set on `headers.Authorization` when configured; absent when not. No empty-string sentinel.
+- ❌ Tab id over-triggering in diff predicate — predicate only matches against dashboardAPI's own id + child + grandchildren, never tab ids. Verified.
+
+## Migration plan applied
+
+This manifest is created together with slice #43 — the new outputs added in slices #34–#42 are documented here. Other EVOLV nodes still need their own manifests; tracked in `IMPROVEMENTS_BACKLOG.md`.
