Alexander Kharkevich 528c3278b7 fix(iam): allow colons and dots in STS claim policy names (#3164)
`is_safe_claim_policy_name` rejected any character other than
`[a-zA-Z0-9_-]`, silently dropping policy names containing colons.
This breaks Kubernetes workload identity where `claim_name=sub`
resolves to `system:serviceaccount:<namespace>:<sa-name>` — a valid
policy name that can be created via the admin API but is then
unreachable during STS session authorization.

Add `:` and `.` to the allowed character set. These characters are:
- Used in K8s service account `sub` claims (colons)
- Used in Java/DNS-style group names from OIDC providers (dots)
- Already accepted by the `add-canned-policy` admin API endpoint

Require at least one alphanumeric character to prevent meaningless
names (`.`, `..`, `-`, `_`, `:`, etc.) from resolving.

Still rejected: `/`, `\`, whitespace, `$`, `;`, `{`, `}` and other
chars that could enable path traversal or injection.
