Walkthrough

This PR updates version badges across 7 Helm charts (Agent, Cloudprem, Console-V3, Core, Membership, Portal, and Stargate) and refactors Helm hook annotations in the Core chart by extracting them into a shared template definition.

Changes

Version Badge Updates README.md, charts/agent/README.md, charts/cloudprem/README.md, charts/console-v3/README.md, charts/core/README.md, charts/membership/README.md, charts/portal/README.md, charts/stargate/README.md	Updates version badges across 8 README files: Agent (2.11.1 → 2.12.0), Cloudprem (4.0.0-beta.20 → 4.0.0-beta.21), Console-V3 (3.0.0-beta.14 → 3.0.0-beta.15), Core (1.4.0 → 1.5.0), Membership (3.0.0-beta.7 → 3.0.0-beta.8), Portal (3.0.0-beta.15 → 3.0.0-beta.16), Stargate (0.9.1 → 0.10.0).
Core Template Refactoring charts/core/templates/_job.tpl, charts/core/templates/_postgres.tpl	Introduces new core.job.annotations template for pre-upgrade Helm hook metadata; refactors core.postgres.job.annotations and core.postgres.job.sa.annotations to delegate to this shared template instead of embedding hook logic inline.
