[Minor] Migrate src/plugins/lua/bimi.lua to lua_shape

Replace tableshape with lua_shape in BIMI plugin.

Changes:
- Uses lua_redis.enrich_schema() which returns lua_shape with mixins
- ts.string, ts.boolean, ts.number → T.string(), T.boolean(), T.number()
- ts.number + ts.string / fn → T.one_of({T.number(), T.transform(T.string(), fn)})
- :is_optional() → :optional()
- Added comprehensive documentation to all fields

Schema: settings_schema with Redis common fields plus BIMI-specific
settings for helper service URL, timeouts, VMC-only mode, and staged
HTTP timeouts (connect, SSL, write, read).
