Rename sqlite_history module to history (#17)

* Rename sqlite_history module to history.

Drop the sqlite-specific prefix now that history collection is the primary module name across SDK, tests, and docs.

* Address PR review feedback for history module rename.

Add a sqlite_history compatibility shim, clarify docs naming, and align the
module docstring with the collect-history SQLite scope.

* Remove sqlite_history compatibility shim.

The rename to mt5cli.history is intentionally breaking; downstream code
should update imports rather than rely on a deprecated re-export path.
