enhance: consolidate wp_options into serialized arrays

Reduce ~18 individual wp_options rows to 5 by storing settings in
serialized arrays (workos_production, workos_staging, workos_global)
plus two standalone rows (workos_active_environment, workos_db_version).

Adds stellarwp/arrays dependency for Arr::get/set helpers and an
Options abstraction layer (Options\Production, Staging, Global_Options)
registered as container singletons. Includes v3 schema migration that
consolidates existing individual options into the new format.
