* fix: filter empty strings from allowed groups
When parsing allowed groups from configuration (e.g., via environment
variable OAUTH2_PROXY_ALLOWED_GROUPS), viper may include empty
strings in the parsed slice when trailing commas are present
(e.g., "group2," becomes ["group2", ""]).
The setAllowedGroups function now filters out empty strings before
adding them to the AllowedGroups map, ensuring that only valid group
names are checked during authorization.
Fixes#3123
