The operator has read GRID_SIGNALS_PEER_INTERVAL_SECS since before this, but no chart value set it, so a deployment could not change the cadence. Every site polls every other alive site, so a grid of N sites makes N*(N-1) polls each interval: 6 at three sites, 90 at ten, 2450 at fifty, each one an mTLS fetch. The interval is the only lever on that, and it was unreachable. Empty keeps the operator's own default, so nothing changes for an existing install. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>

The value reaches clap as a u64 with env GRID_SIGNALS_PEER_INTERVAL_SECS, so a negative or non-numeric one makes the operator fail its own argument parse at startup, and the schema accepted both. Zero was worse than rejected: Helm's with block treats it as empty and drops it, so asking for no delay silently got the 30 second default. The schema now takes a positive integer or an empty string, matching the oneOf the metrics block already uses, with the three refusals and the floor tested.

A positive-integer pattern still accepted 18446744073709551616, which overflows the u64 clap parses it into, so the operator failed its argument parse on a value the schema had just approved. Both branches now take 1 to 99999, which is a day and change and far inside u64, so the integer and string forms agree. Signed-off-by: Sam Batschelet <sbatsche@redhat.com>

Document the accepted value types.
The schema accepts an integer or a string, including "", but this row lists only int. Update the type to int or string so the documented contract matches the schema. As per path instructions, prioritize “public API and compatibility implications.”

Add an integration test for signals.peerIntervalSeconds.
This PR adds a chart option and maps it to the operator container’s GRID_SIGNALS_PEER_INTERVAL_SECS. The new tests check rendered templates, but no integration test configures this option. Add a deployment-level test that sets the option and checks that the deployed operator receives the configured value.
