Misaka_Company 1f7191421a feat: access reader and value serialization ...

Add to_jsonable() (Access/pyodbc value -> JSON-safe) with strict TDD
(5 tests: datetime iso, bool preserved before int, decimal->str,
none/numbers, dict round-trip). bool branch precedes int because bool
is a subclass of int in Python.

Add AccessReader: reads TableChangeLog (read_log), reads a full source
row by RecordID via to_jsonable (read_row, warns on >4000-char values
that JSON_VALUE would truncate), and deletes processed log IDs in
chunked, retried batches (delete_log_ids, no-op on empty list).
Connects via the ACE ODBC driver from config.access.driver, shared
autocommit mode to coexist with the live .laccdb client.

Integration test against the real 氩弧焊.accdb (read-only; delete_log_ids
only exercised with []) passes.
