10. doc: fix How to Upgrade section for bitcoin wrapper and libexec

    Since #31375, Linux installs ship a bitcoin wrapper in bin/ that dispatches to multiprocess binaries in libexec/. Copying only bitcoind/bitcoin-qt leaves those stale. Tell users to copy over bin/ and libexec/ instead.
    
    Fixes #36431.

    There's a number of conflicts here, so I might do this separately.

13. test: characterize proxy network name errors

    The `-proxy` error lowercases unsupported network names, unlike `-onlynet` and `getnodeaddresses`.
    Also cover rejection of the `tor` name removed in #34031, mixed-case `onion` acceptance, I2P exclusion, and clearing the IPv4 and name proxies together.

14. refactor: share proxy network parsing

    Use the shared network parser to select each per-network proxy, matching `-onlynet` and `getnodeaddresses`.
    Keep accepted names, proxy assignments, and error messages unchanged.

15. net: preserve network name case in proxy errors

    `-proxy` lowercases unsupported network names in its error message, unlike `-onlynet` and `getnodeaddresses`.
    Let the shared parser handle case-insensitive matching so the diagnostic retains the user's spelling.

16. doc: use onion in proxy help and examples

    `tor` was removed as a network name in #34031, but the proxy help and Tor examples still advertise it.
    Use canonical network names in the help and document `onion` with the removal reference.

    These all look correct to me.

    All commits are present, attributed, and range-diff differences are metadata or expected target-branch adaptations.
