Move versioning from Rails initializer to .sure-version file (#1587)

* Extract version to .sure-version file and add Sentry release tracking

Move the hardcoded version string to a `.sure-version` file at the repo
root so it can be read by both the Rails version initializer and other
tooling. Configure `config.release` in the Sentry initializer to tag
errors with the app version.

* Use .sure-version as single source of truth in Helm CI workflows

Update chart-ci, chart-release, and publish workflows to read the app
version from .sure-version instead of regex-parsing version.rb. The
pre-release bump job now writes directly to .sure-version and stages it
for commit.

* Guard empty .sure-version fallback

* fix: sync Helm chart version with .sure-version

* Moving on to `v0.7.1-alpha.*` with this

* Defensive rescue

* Getting fancy with versions now
