Extract availabilityZoneLiveCount from Ev2 central config

[Gerd Oberlechner (geoberle)]

Summary

• Add availabilityZoneLiveCount to the sanitized Ev2 region config, alongside the existing availabilityZoneCount, so we know the real (live) number of AZs in a region, not just the planned count.
• Lowercase region name keys during sanitization — the central config has a couple of regions with inconsistent casing (Finlandcentral, Netherlandsnortheast) which broke the lowercase convention used everywhere else.
• Regenerated config/ev2config/config.yaml for both the public and ff clouds from fresh Ev2 central config exports.

Test plan

• make test
• make lint

🔵 Needs a closer look

The embedded Ev2 config YAML adds availabilityZoneLiveCount for public but not for ff, which will break template execution for ff contexts if the new key is referenced due to missingkey=error.

Pull request overview

This PR updates the Ev2 config sanitization pipeline to surface a new per-region field (availabilityZoneLiveCount) representing the live (actual) number of availability zones, and normalizes region name keys to lowercase to match existing conventions and avoid casing inconsistencies from the central config export.

Changes:

• Added availabilityZoneLiveCount to the sanitized region config output and regenerated the public cloud Ev2 config YAML accordingly.
• Lowercased sanitized region map keys (region.Name) during sanitization to enforce consistent lowercase region identifiers.
• Updated the embedded Ev2 config YAML (config/ev2config/config.yaml) for public with the refreshed central config export.

config/ev2config/config.yaml:115

• availabilityZoneLiveCount is added for public regions, but the ff cloud region entries earlier in this same file still do not define availabilityZoneLiveCount. Because config preprocessing executes templates with missingkey=error, any template that starts using .availabilityZoneLiveCount will fail for ff contexts due to the missing key. To keep the schema consistent across clouds, add availabilityZoneLiveCount to all ff regions as well (even if temporarily equal to availabilityZoneCount until a refreshed central config export is available).

🟢 Approval recommended

The changes are additive, consistent with existing config consumption patterns, and appear correctly propagated into the regenerated embedded Ev2 config.
