xBase writes to MariaDB/MySQL: numeric and logical setters reach the staging buffer

AdsSetDouble, AdsSetLong, AdsSetLongLong and AdsSetLogical had
no MariaDB branch and fell through to the native-DBF table lookup,
failing with 5000 unknown table on mariadb:// tables. REPLACE
on numeric and logical fields was impossible; character and date
fields already worked because AdsSetString (and the date setters
that delegate to it) staged through the backend.

They now stage through MariaConnection::set_field, exactly like
AdsSetString: doubles are formatted with "%.17g" (round-trip
exact) and logicals as "1"/"0", which MariaDB coerces into both
numeric (TINYINT) and CHAR(1) columns; AdsGetLogical accepts
both forms on read. This completes the xBase write path over MariaDB:
APPEND BLANK + REPLACE + commit now works for every field type.

Changes

• src/abi/ace_exports.cpp — OPENADS_WITH_MARIADB branches in
  AdsSetDouble, AdsSetLong, AdsSetLongLong, AdsSetLogical.
• tests/unit/abi_plus_mariadb_write_test.cpp — live-server
  regression: numeric/logical INSERT and UPDATE round-trip through
  the setters, plus AdsLockRecord/AdsUnlockRecord contention
  between two MariaDB sessions. Skips cleanly without a server.

Inter-process .ntx index lock, Harbour DBFNTX-compatible

The NTX driver now locks the .ntx file itself at byte
1,000,000,000, the same scheme Harbour's DBFNTX uses, so OpenADS,
Harbour and xHarbour/Clipper applications can share NTX indexes
across processes safely: reads take a shared lock, writes an
exclusive one held until flush(), and a version counter lets other
processes notice the change and reload the index. Before this, only
DBF record locks were aligned across processes and concurrent
writers could corrupt an .ntx.

Changes

• NTX driver: inter-process lock implementation + header.
• New inter-process unit tests, including a two-process concurrent
  writer test.

Test Results

• New suites: MariaDB setter round-trip (live-server gated) and NTX
  inter-process lock cases.
• Full matrix (Windows MSVC x64/x86, Linux, macOS) runs in CI on the
  tag push.
