fix: tighten openid-connect-php constraint to ^1.0.2 (SEC_REVIEW F23)
The previous `^1.0` constraint matched v1.0.0 / v1.0.1, which carry
the iss-confusion advisory fixed in v1.0.2. `composer.lock` already
resolved to v1.0.2 in practice, but a future `composer update` would
have been free to drift backwards within the major. The new
`^1.0.2 || ^2.0` constraint floors the line at the patched release
while preserving an upgrade path to a future v2.x.
`composer audit --no-dev` was already wired into `scripts/ci.sh` for
both api and ui, so any new advisory against the locked version
fails CI.
