Enhance parseCIDR in utils/ipallowlist.go to support single IP addresses
(without CIDR prefix) and ensure IP is in canonical form. This matches
the functionality previously in access.go.
- Add ParseCIDR as public function supporting CIDR and single IP
- Update access.go to use utils.ParseCIDR instead of local implementation
- Remove duplicate parseCIDR function from access.go
- Update tests to use utils.ParseCIDR

Extract duplicate b2s/s2b functions from proxy/utils.go into
internal/utils/bytes.go. These are zero-allocation unsafe conversions
for byte slice <-> string conversion.
- Create utils.B2s() and utils.S2b() as unified implementations
- Update proxy/utils.go to call utils functions
- Add safety documentation about shared memory warning

Extract duplicate generateETag function from handler/static.go and
cache/file_cache.go into internal/utils/etag.go. Both functions were
identical, using strconv.AppendInt for zero-allocation ETag generation.
- Create utils.GenerateETag(modTime, size) as the unified implementation
- Update handler/static.go to call utils.GenerateETag
- Update cache/file_cache.go to call utils.GenerateETag
- Remove unused strconv import from static.go
