ce024b1c0ef2dcd307023aaaab40373c8bf17db1 test: MiniWallet: force P2PK signature to have fixed size (71 bytes) (Sebastian Falbesoner)
Pull request description:
This PR is a follow-up to #21945. It aims to both fix the fee calculation for P2PK mode transactions and enable its vsize check. Currently, the latter assumes a fixed tx length, which is fine for anyone-can-spend txs but doesn't apply to P2PK output spends due to varying DER signature size; the vsize check is therefore disabled for P2PK mode on master branch.
Creating one million DER signatures with MiniWallet shows the following distribution of sizes (smart people with better math skills probably could deduce the ratios without trying, but hey):
| DER signature size [bytes] | #occurences (ratio) |
| ------------- | ------------- |
| 71 | 498893 (49.89%) |
| 70 | 497244 (49.72%) |
| 69 | 3837 (0.38%) |
| 68 | 22 (0.0022%) |
Note that even smaller signatures are possible (for smaller R and S values with leading zero bytes), it's just that the probability decreases exponentially. Instead of choosing a large vsize check range and hoping that smaller signatures are never created (potentially leading to flaky tests), the proposed solution is ~~to limit the signature size to the two most common sizes 71 and 70 (>99.6% probability) and then accordingly only check for two vsize values; the value to be used for fee calculation is a decimal right between the two possible sizes (167.5 vbytes) and for the vsize check it's rounded down/up integer values are used.~~ to simply grind the signature to a fixed size of 71 bytes (49.89% probability, i.e. on average each call to `sign_tx()`, on average two ECC signing operations are needed).
~~The idea of grinding signatures to a fixed size (similar to https://github.com/bitcoin/bitcoin/pull/13666 which grinds to low-R values) would be counter-productive, as the signature creation in the test suite is quite expensive and this would significantly slow down tests that calculate hundreds of signatures (like e.g. feature_csv_activation.py).~~

6e63e366d609312ab984b4439de2d59bb618620b test: refactor: dedup utility function chain_transaction() (Sebastian Falbesoner)
Pull request description:
Both tests `mempool_packages.py` and `mempool_package_onemore.py` define a utility function `chain_transaction` with a similar implementation. This PR deduplicates it by moving it into the util package and keeping the more general properties:
* pass a list of parent_txids/vouts instead of single values
* always mark the BIP125-replaceable flag for txs, created via `createrawtransaction` (this is needed by the `mempool_package_onemore.py` test, but doesn't hurt the other one)
This is a low-hanging fruit; as a potential follow-up one could probably also deduplicate the function `chain_transaction` in `rpc_packages.py`, which looks a bit different, as it also takes the parent locking script into account and doesn't send the tx.

493fb47c577b7564138c883a8f22cbac3619ce44 Make SetupServerArgs callable without NodeContext (Russell Yanofsky)
Pull request description:
`bitcoin-gui` code needs to call `SetupServerArgs` but will not have a `NodeContext` object if it is communicating with an external `bitcoin-node` process, so this just passes `ArgsManager` directly.

Pull request description:
Run mempool_reorg.py test even when the wallet is disabled, as discussed in #20078.
As part of this PR I created a new method in `MiniWallet`, `create_self_transfer`, to return a raw tx (without broadcasting it) and its associated utxo.

5a1bef60a03b57de708a1a751bd90b8245fd8b83 test: refactor: remove binascii from test_framework (Zero-1729)
Pull request description:
This PR continues the work started in PR #22593, regarding using the `bytes` built-in module. In this PR specifically, instances of `binascii`'s methods `hexlify`, `unhexlify`, and `a2b_hex` have been replaced with the build-in `bytes` module's `hex` and `fromhex` methods where appropriate to make bytes <-> hex-string conversions consistent across the functional test files and test_framework.
Additionally, certain changes made are based on the following assumption:
```
bytes.hex(data) == binascii.hexlify(data).decode()
bytes.hex(data).encode() == binascii.hexlify(data)
```
Ran the functional tests to ensure behaviour is still consistent and changes didn't break existing tests.
