[Fix] compiler errors and warnings

[QuangHaiNguyen]

• Activate several common build flag (check CMake file in src)
• Fix all compiler errors/warnings

[Copilot]

Pull request overview

This PR aims to make the framework build cleanly under stricter compiler settings by enabling common warning/security flags in CMake and addressing a broad set of compiler warnings/errors across core modules and unit tests.

Changes:

• Enable stricter GCC/Clang compile flags (including -Werror) and adjust per-file options where needed.
• Fix numerous warnings via unused-parameter handling, type casts, pointer arithmetic fixes, and API type alignment.
• Update versioning metadata (project/version header) and remove an unused assert source unit.

src/service/event_bus/ez_event_bus.c:287

• event_data_size is size_t but is cast to uint32_t when reserving queue space. Combined with ezQueue_ReserveElement allocating via a uint16_t allocator, large payloads can truncate and then memcpy() will overflow the reserved buffer. Add explicit bounds checks for event_data_size (<= UINT16_MAX if using ezStaticAlloc) and return an error when exceeded, instead of truncating.

    
    q_element_event_code = ezQueue_ReserveElement(&event_bus->event_queue, &code, sizeof(uint32_t));
    q_element_data = ezQueue_ReserveElement(&event_bus->event_queue, &data, (uint32_t)event_data_size);

    if(q_element_event_code == NULL || q_element_data == NULL)
    {
        EZWARNING("Cannot reserve event queue element");
        ezQueue_ReleaseReservedElement(&event_bus->event_queue, q_element_event_code);
        ezQueue_ReleaseReservedElement(&event_bus->event_queue, q_element_data);
        return false;
    }

    *(uint32_t*)code = event_code;
    memcpy(data, event_data, event_data_size);
