add partial import export and config preview

[tylerpieper]

Added the -y/--yes argument to skip prompts (used during config import)
Added --include-settings and --exclude-settings and filter to the binary protobuf both upon export and import. When configuring using a .cfg file and -y is omitted, the CLI will now output the config differences and prompt "Apply these changes to the node? [y/N]" before modifying any hardware settings. YAML files are skipped from the preview flow.

Summary by CodeRabbit

• New Features
  • Added options to selectively include or exclude settings during configuration import and export.
  • Added a confirmation prompt before applying binary configuration profiles, with a --yes option to bypass confirmation.
  • Exported configuration files in binary/protobuf mode can now be subset-filtered to include only the selected settings.

📝 Walkthrough

Walkthrough

Adds selective DeviceProfile configuration import/export through include/exclude selectors, confirmation for binary profile application, and a --yes bypass option.

Changes

Selective configuration profiles

Layer / File(s)	Summary
CLI options and configuration entry points meshtastic/__main__.py	Adds --include-settings, --exclude-settings, and -y/--yes, then filters imported profiles before application.
DeviceProfile filtering meshtastic/__main__.py	Adds filter_profile to map aliases and nested selectors while clearing unselected or excluded protobuf fields.
Binary import and export integration meshtastic/__main__.py	Requires confirmation before applying filtered binary profiles and applies filtering before binary serialization.

Estimated code review effort: 3 (Moderate) | ~20 minutes

In `@meshtastic/__main__.py`:
- Around line 1497-1580: Fix filter_profile so overlapping include entries merge
safely, preserving all-subfields semantics when a base is included alongside
specific subfields instead of calling add on None. Group top-level aliases by
their mapped protobuf field and clear each underlying field only when none of
its aliases are included. Normalize include bases consistently when matching
config and module_config fields, including underscore-less aliases, and use the
normalized key to apply subfield filtering. Apply the same normalization and
alias-aware lookup in the excludes branch so underscore-less and camel-case base
or subfield names clear the intended fields.
