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.
