[FIX] mail: remove JS record proxy in favor of accessors

- accessors are defined only once on the model
- they work per field which avoids having to check if target param is in fields
  at every read/write on record

Also store fields as list in `__fieldList` to quickly iterate them without
`Object.values`.

`__combinedFields` are now renamed to `__fieldMap` instead of just `fields` to
avoid confusion with fields definition, and to have a naming similar to
`__fieldList`.

Part of task-2308312
