feat(functions): support custom JSON encoder and decoder (#975)

* feat(functions): support custom JSON encoder and decoder

Previously, FunctionInvokeOptions always used a default JSONEncoder()
when encoding Encodable request bodies, with no way to customize
encoding strategies (e.g. snake_case keys, custom date formats).

This adds encoder/decoder parameters to:
- FunctionInvokeOptions body initializers
- FunctionsClient initializers
- SupabaseClientOptions.FunctionsOptions

The client-level decoder is also used as the default for the
invoke<T: Decodable> method, replacing the per-call JSONDecoder()
default.

Made-with: Cursor

* fix(functions): remove unused client-level encoder from FunctionsClient

The encoder stored on FunctionsClient was never used during request building
since body encoding happens inside FunctionInvokeOptions. Remove it and keep
only the decoder (which IS used in invoke<T: Decodable>). Per-call encoding
is still fully supported via FunctionInvokeOptions(body:encoder:).
