Change Description

Add FW_PARAM_OK, a shared macro that reports whether an Fw::ParamValid value is VALID or DEFAULT. Replace the existing equivalent checks throughout the framework and service components, and add unit coverage for all four parameter-validity states.

Rationale

Parameter consumers repeatedly spell out the same validity condition. Centralizing it removes boilerplate and gives parameter checks one consistent expression.

Testing/Review Recommendations

• fprime-util format --check on all changed C++ files
• fprime-util check --all (129/129 tests passed)
• Review that FW_PARAM_OK accepts only VALID and DEFAULT

Future Work

None.

AI Usage (see policy)

OpenAI Codex was used to inspect the issue and repository, implement the macro and unit test, refactor existing checks, run formatting and the full test suite, and prepare this pull request. The submitted code and prose were generated by the AI agent and validated against the repository's pinned toolchain.

@bocchino This implements #5573 and is ready for maintainer review. GitHub is holding the Actions workflows for first-time-contributor approval; please approve the runs when convenient. The branch is current with devel, the repository-pinned format check passes, and fprime-util check --all passes 129/129 tests locally.

Thanks @LeStarch for confirming the CCB approval and reopening this.

I rebased the contribution cleanly onto current devel (1013197e99) and pushed the updated head (f391264d86). Fresh local validation on the rebased branch:

• repository format check on all eight changed C/C++ files: passed
• fprime-util check --all: 131/131 tests passed

@bocchino, this is ready for maintainer review. GitHub currently shows no check runs on the new head, so the first-time-contributor workflows still need maintainer approval before the automated gates can report.
