feat: secret patterns for all of a repo's config files, with per-type overrides

providers.repos.secretPatterns (keys, values) apply to every config file
type; spring.secretPatterns overrides them list by list. A repo's
.lazysecrets.yaml takes the same layout. Each list comes from the first
that sets it: the repo's for the type, the repo's, the config's for the
type, the config's, the defaults.

Replaces the unreleased providers.repos.spring.keys/values.
