📄 Description

Describe your changes

Access restrictions on reverse-proxy services currently combine the different allowlists with AND, so a connection must match every configured allowlist. That makes rules like "allow country X OR CIDR Y" impossible to express, and adding a CIDR allowlist silently denies country-allowed clients (and vice versa). This adds an allow_match option to control how the allowlists combine.

Add allow_match to access restrictions: all (default, AND) requires matching every allowlist, any (OR) requires matching at least one, e.g. an allowed country or an allowed CIDR
Keep blocklists as a hard deny regardless of the mode, and fall back to all for an empty or unknown value so behavior never loosens unexpectedly
Preserve existing behavior for services with no allow_match set (treated as all)

Summary by CodeRabbit

New Features
- Added allow_match to access restrictions to control allowlist combination: all (AND) or any (OR), with all as default.
Bug Fixes
- Improved validation and consistent legacy/empty handling for allow_match.
- Fixed service restriction loading from storage so configured restrictions persist correctly.
Tests
- Added coverage for allow/deny semantics, API/proto round-trips, geo/crowd control behavior, validation failures, and storage persistence.
