feat: add OpenVox View dashboard alongside Puppetboard

[sratslla]

Fixes #19

Summary

• Adds OpenVox View support to openvox-helm-chart as an additional optional dashboard (Option B), without removing existing Puppetboard support.
• Introduces openvoxview.* values (image/tag/port/resources/env/ingress/securityContext) to enable/disable OpenVox View independently.
• Deploys OpenVox View as a sidecar container in the PuppetDB pod, mounts PuppetDB certs, and exposes it via the PuppetDB service on port 5000.
• Adds an optional openvoxview ingress template and helper labels.
• Updates README with configuration and usage examples.

Just saw this PR missed it when I created the issue. We have implemented it in slightly different approach. Lemme know how you wanna take this forward.

I have to say i prefer this implementation method as it allows users the choice and allows us a transition path (e.g. leave puppetboard default, then switch to openvoxview as default, then later remove puppetboard)

@JGodin-C2C wanting to draw your attention to this for any input you may wish to add

I haven't reviewed yet but please ensure that default remains puppetboard at this time

[anthonysomerset]

I am happy with the change, please update the unit tests and bump the version number like other merged changes and push to this PR

[JGodin-C2C]

Yep, overall the MR seems solid ( i left a comment, but that kinda splinting hairs ) .
For next improvement (in another MR ).

• Ability to setup "custom requests" as documented here : https://github.com/voxpupuli/openvoxview/blob/main/CONFIGURATION.md as this feature is AWESOME
• Ability to setup "views" for the same reasons as previous point

So, kudos for the new code.

I have made the suggested changes, please have a look.
Thanks!
