* Fix duplicate port names in controller-manager containers
Multiple controller-manager containers were using the same "heathz" port
name, causing Kubernetes warnings about duplicate ports in the
StatefulSet. This also affected the prometheus port "prom-cm".
Changes:
* Renamed healthz port to hp-cm (health port - controller manager)
* Renamed prom-cm to pm-cm for consistency
* Addedd {{ .portSuffix }} variable to differentiate external controller
ports
* Implemented port suffix logic
The suffix logic handles cluster names by:
1. Names <9 chars: use full name as suffic
* e.g.: child01 -> -child01
2. Names with trailing numbers: preserve the number format users chose
* Detects 1-2 digit numbers with optional hyphen
* Truncates base name to fit within 15 chars
* e.g.: verlongcluster-01 -> -verylo-01
3. Names without numbers: use SHA-256 hash for uniqueness
* Trunactes name to 5 chars and appends 3-char hash
* e.g.: verlongclustername -> -veryl-a3f
The logic separates container suffix (full name) from port suffix
(truncated) so container names remain descriptive while port names stay
compliant.

* Add optional port name overrides for ext. controller
The auto-generated port name suffixes for external controller manager
can collide when cluster names are similar, as the 3-character has
provides only 4,096 possibilities. With the optional healthPortName and
prometheusPortName fields to cluster configuration, allows users to
explicity set port names when automatica generation creates collisions.

* Fix portSuffix generation
Changed from "and" to "or", so portSuffic is calculated when either
healthPortName or prometheusPortName is unset.
