feat(netflix): support templated Android ESN generation

Browse Source 
Add support for `{randomchar_N}` placeholders in Netflix Android `esn_map` values and generate those segments at runtime. Reuse a cached ESN only when it matches the derived template pattern, is Android-typed, and is not expired; otherwise regenerate and refresh the cache.

This keeps static ESN mappings working as before while enabling dynamic ESN templates (e.g., system_id `7110`) to avoid fixed identifiers and keep ESNs valid per template.
