Add language, base address, and loader support for raw firmware import

Wire GHIDRA_LANGUAGE, GHIDRA_BASE_ADDRESS, GHIDRA_LOADER through the
Docker entrypoint and MCP tools so raw binaries (e.g., ARM7TDMI firmware)
get the correct processor, memory map, and loader instead of relying on
auto-detection. Auto-sets BinaryLoader when language is specified.

Input validation at both Python and bash layers prevents malformed values
from reaching analyzeHeadless.
