[chore][INF-7329] Allow selectively sending telemetry inputs to Retool

[golfdish]

Counterpart to https://github.com/tryretool/retool_development/pull/67405: allow selectively enabling telemetry inputs to be sent to Retool when telemetry.sendToRetool.enabled = true, with only metrics enabled by default.

Note that collecting telemetry is still disabled by default.

Confidence Score: 5/5

Safe to merge — the change is additive, guarded by a Helm-level validation, and defaults preserve existing behaviour.

The only moving part is a new env var conditionally injected when sendToRetool is enabled. The fail guard prevents misconfiguration, the default value of ["metrics"] keeps current opt-in deployments unaffected, and the template logic is straightforward with no side effects on other chart components.

No files require special attention.
