### What

Upgrade workflows to use `macos-15-*` rather than `macos-13`

### Why

1. It's about to be deprecated: [announcement
🔗](actions/runner-images#13046)
2. It's already making the CI fail: [example run
🔗](https://github.com/stellar/stellar-cli/actions/runs/19081484092/job/54516597745?pr=2275)

### Notes on Runner Compatibility

After extensive testing across macOS runner types:

| Runner | Result | Notes |
|:--|:--:|:--|
| ✅ **macos-15-large** | ✅ **Passes** | Stable with full setup. |
| ✅ **macos-14** | ✅ **Passes** | Works consistently. |
| 🟠 **macos-15-intel** | ⚠️ **Intermittent** | Suitable for lighter
setups but fails under heavier load — `-large` is usually more stable. |
| 🟠 **macos-15** | ⚠️ **It depends** | Does **not** support nested
virtualization (required by Lima/QEMU), so cannot be used in some
setups. |

### ⚠️ Disabled Job

I couldn't make the ledger-emulator.yml workflow succeed for macos
despite many attempts, so it was temporarily disabled, to be re-added in
#2299.

### What
Replace the custom data_into_key function with LedgerEntry's built-in
to_key method and remove the 86-line helper function along with its
associated imports.

  ### Why
The stellar-xdr library now provides a native to_key method on
LedgerEntry, eliminating the need for a custom implementation that
manually converts each LedgerEntryData variant to its corresponding
LedgerKey.

Fixes #1588 

Refactors generated help example and usage notes to accommodate self-referencing custom types.

### What

closes #2021

related rpc-client pr:
stellar/rs-stellar-rpc-client#57

Updates the topic filter structure that is being passed to the rpc
server `getEvents` method, to align with it's expected API.

The GetEventsRequest, from the rpc server, is expecting the topics to be
an array of TopicFilters, and a TopicFilter is an array of
SegmentFilters. So it is expecting an array of arrays.

### Why
We are currently just passing in a segment filter, without nesting it in
an array of arrays, and are seeing an error when doing so.

Updates the `md-gen` alias to specify that `doc-gen` is it's own
package, similar to `make docs`.

### What
closes #1840 

Changes the `config.sign` signature to also accept a boolean "quiet"
value.

### Why

So we can pass that value through to `sign_with.sign_tx_env` and respect
the `quiet` config when printing.

### Known limitations

n/a

### What

Minor improvements to RPC tests, patching secure store
intermittent CI failures, and allowing all container types to run on
release PR updates.

### Why

Failure rate of RPC tests is ~30% in CI pipelines, and a few tests have
remained ignored without issues

### Known limitations

Slightly increase CI minutes as now 3 container types will run RPC tests
on release PRs as well
