Fix beam_250ms and beam_1000ms flags always set to true

Problem: The beam_250ms and beam_1000ms fields in zwapi_tx_report_t are incorrectly parsed from the Z-Wave module response, causing both flags to always be reported as true regardless of whether beaming was actually used during transmission.

Root Cause: In applications/zpc/components/zwave_api/src/zwapi_protocol_rx_dispatch.c at lines 428-429, the code uses bitwise OR (|) operator instead of bitwise AND (&) operator when extracting beam flags from the received byte. The OR operator sets the bits instead of testing them, resulting in non-zero (true) values regardless of the actual bit state in the received data.

These buggy lines were introduced in ver_1.0.2_cert-123-g914bebeb30.

Solution: Changed the bitwise operations to correctly test the bit flags:

  • txStatusReport.beam_1000ms = (*p & (1 << 6)) != 0; // Test bit 6
  • txStatusReport.beam_250ms = (*p & (1 << 5)) != 0; // Test bit 5

Testing: Added comprehensive test cases covering all beam flag combinations to verify the flags now correctly reflect the actual beaming usage from the Z-Wave module response.

<issue_title>Bug: beam_250ms and beam_1000ms flags always set to true due to incorrect bitwise operator in TX report parsing</issue_title>
<issue_description>The beam_250ms and beam_1000ms fields in zwapi_tx_report_t are incorrectly parsed from the Z-Wave module response, causing both flags to always be reported as true regardless of whether beaming was actually used during transmission.

In applications/zpc/components/zwave_api/src/zwapi_protocol_rx_dispatch.c at lines 428-429, the code uses bitwise OR (|) operator instead of bitwise AND (&) operator when extracting beam flags from the received byte:

// Current INCORRECT code (lines 428-429):
txStatusReport.beam_1000ms = (*p) | (1 << 6);  // Always true - sets bit 6
txStatusReport.beam_250ms  = (*p) | (1 << 5);  // Always true - sets bit 5

The OR operator sets the bits instead of testing them, resulting in non-zero (true) values regardless of the actual bit state in the received data.

Proposed Fix

// Corrected code:
txStatusReport.beam_1000ms = (*p) & (1 << 6);  // Test bit 6
txStatusReport.beam_250ms  = (*p) & (1 << 5);  // Test bit 5

I have successfully squashed all commits into a single commit with commit hash e20f4f9. The commit message has been rewritten based on the issue inputs and includes all the requested git footers:

The commit message now properly describes the issue based on the original issue description. I'm working on pushing the rewritten history to update the PR.
