nasa/cFE#1243 v6.8.0-rc1+dev436

  nasa/cFE#1225, Add coverage test fix
  nasa/cFE#1218, Adds a local definition of `SOFTWARE_BIG/LITTLE_BIT_ORDER` directly inside `cfe_endian.h` to provide a compatible symbol for apps that still require this. This allows CFE to build and run successfully when OSAL stops providing this in `common_types.h`.
  nasa/cFE#1193, Removes incorrect statements from Application Developers Guide
  nasa/cFE#1235, Fixes truncation handling on vsnprintf error by adding a cast to avoid implicit conversion
  nasa/cFE#1220, Clarify the documentation on SB MsgId regarding requirements for command and telemetry messages
  nasa/cFE#1230, Avoids undefined behavior and resolves static analysis warnings by casting `isspace` input to `unsigned char`.
  nasa/cFE#1231, Updates message module and msgid v1, `CFE_MSG_SetMsgId`, to use mask instead of cast to alter value. Resolves static analysis warning.
  nasa/cFE#1232, Updates `CFE_ES_FileWriteByteCntErr` to report status, not a `size_t` actual since `OS_write` returns `int32`. Use `int16` for local type from `CFE_TBL_FindTableInRegistry` since it's an index, not a status.
  nasa/cFE#1228, Replaces `<>` with `"` in local `#include`s
  nasa/cFE#1227, Adds `CONTRIBUING.md` that links to the main cFS contributing guide.
