Converts 113 [SerializableProperty] members whose setters only coerce the
value, reject it, or run post-change side effects into plain
[SerializableField] declarations using allowFieldChange and fieldChanged.
Wire- and schema-neutral: the migration schema regeneration produces zero
changes.
Kept as hand-written properties: custom getters (fallback defaults, lazy or
self-healing reads), virtual/override members, pre-assignment state capture
(durability unscale/scale sandwiches), and setters with exotic semantics
(work on equal assignment, early returns that skip persistence).
Behavioral notes: generated setters skip all work when the incoming value
equals the field, and always MarkDirty on change - a handful of converted
setters previously never marked dirty (their changes only persisted if
something else dirtied the entity) or re-ran side effects on equal
assignment.
