fix(editor): escape user strings in server module map/zone/tele SQL

The map_dbc, area_table_dbc, and game_tele INSERTs previously
embedded mapName/displayName/manifest.mapName as raw strings — a
zone called "King's Land" or anything containing a single quote
would emit malformed SQL that AzerothCore would reject. Promotes
the existing escapeSql helper to a public SQLExporter::escape and
uses it in all three INSERTs.
