Bump Wails v3 to alpha2.117

[unidoc-anom]

Moves the Wails v3 pin from alpha2.103 up to alpha2.117. The Go module and the wails3 CLI install lines in both CI workflows move together so the CLI and library stay on the same version.

Regenerated the bindings with wails3 generate bindings -clean=true and the diff came back empty, so the Go/JS wire contract is unchanged. Left @wailsio/runtime at alpha.79 since npm doesn't publish an alpha2 runtime and I didn't want to invent a version string that doesn't exist.

Full gate is green locally: go vet, golangci-lint, go test -race, the per-suite test loop, tsc, Vitest, ESLint, and a host wails3 build. I also added a small test module that pins the go.mod and workflow versions and re-checks binding presence and wire shapes, so a later bump can't quietly move the wire contract without the tests catching it.

Still open before merge: the manual desktop smoke on macOS and Windows. CI can't exercise the WebView, and Windows/WebView2 is where past bumps have broken, so I'd like it verified there before this goes in.

Pull request overview

This PR bumps the Wails v3 dependency and CI-installed wails3 CLI from v3.0.0-alpha2.103 to v3.0.0-alpha2.117, and adds a dedicated acceptance-test module to guard version-pin parity and the Go-JSON-to-frontend wire shape across future bumps.

Changes:

• Bump github.com/wailsapp/wails/v3 and align both CI workflows to install wails3@v3.0.0-alpha2.117.
• Update root go.mod / go.sum to reflect the new dependency graph after the bump.
• Add a new independent Go test module (tests/14-2-wails-alpha2-117-upgrade/) that asserts version pins, generated bindings presence/contract, and JSON key casing/value invariants via the built CLI.
