Merge bitcoin#28148: refactor: consistently use ApplyArgsManOptions for PeerManager::Options

8a31597 refactor: deduplicate ignores_incoming_txs (stickies-v)
5f41afc refactor: set ignore_incoming_txs in ApplyArgsManOptions (stickies-v)

Pull request description:

  Consistently use `ApplyArgsManOptions` for `PeerManager::Options`, and initialize `PeerManager::Options` early to avoid reading `"-blocksonly"` twice. Suggested in bitcoin#27499 (comment) and also requested in bitcoin#27499 (comment).

  No behaviour change, but the [`TestingSetup`](https://github.com/bitcoin/bitcoin/blob/e35fb7bc48d360585b80d0c7f89ac5087c1d405e/src/test/util/setup_common.cpp#L255-L256) is now also able to access `"-blocksonly"`.
