chore(vetkeys): split password_manager into self-contained motoko + rust examples

[marc0olo]

Summary

Splits the vetkeys password_manager example into two self-contained examples (one per language) — same restructure as #1443–#1445. Previously it lived only under rust/vetkeys/password_manager/ with a shared Svelte frontend symlinked into motoko/ and rust/ subdirs.

motoko/vetkeys/password_manager/   backend/app.mo + own frontend/ + icp.yaml + mops.toml
rust/vetkeys/password_manager/     backend/ (flattened) + own frontend/ + icp.yaml + Cargo.toml

Why this one differs (no camelCase, no bindgen)

This example uses the Encrypted Maps abstraction. The frontend talks to the backend via the @icp-sdk/vetkeys Encrypted Maps client (DefaultEncryptedMapsClient), not generated bindings — so there's no icpBindgen step. The backend keeps the Encrypted Maps library interface (snake_case), which the SDK client calls verbatim, so there's no camelCase conversion (it's a fixed library API, like the vetKD system API). Both frontends are therefore identical.

Changes

• Frontend (Svelte): per-language copy; canister renamed to backend (env key PUBLIC_CANISTER_ID:backend); dropped eslint/prettier and the BACKEND-env dev logic; root workspace package.json so npm run dev / npm run build run from the example root.
• Motoko: moc 1.11.0 + --default-persistent-actors (dropped persistent); committed backend/backend.did.
• Rust: unchanged; relocated; the .did renamed to backend/backend.did and the Makefile updated to match.
• README split per language (linked prerequisites); test.sh added (query method called with --query); vetkeys-password-manager.yml split into motoko + rust jobs.

CODEOWNERS

Unchanged — /motoko/vetkeys/ and /rust/vetkeys/ both map to @dfinity/core-protocol.

Verification (local)

• Motoko: vite build + deploy, test.sh PASS, and an inserted value survives an upgrade.
• Rust: cargo/wasm build + deploy, test.sh PASS.
• Both frontends build and serve.

Part of the vetkeys split series (#1443, #1444, #1445). Last remaining: password_manager_with_metadata.

Pull request overview

This PR restructures the vetkeys password_manager example into two self-contained examples (Motoko + Rust), each with its own frontend, updated icp.yaml canister naming (backend/frontend), and language-specific build/deploy scaffolding consistent with the other vetkeys split work.

Changes:

• Split the previously shared/symlinked password manager setup into standalone motoko/vetkeys/password_manager/ and rust/vetkeys/password_manager/ example roots.
• Update canister naming and frontend dev-server wiring to target backend (via PUBLIC_CANISTER_ID:backend) and standardize frontend build steps in icp.yaml.
• Add a new Rust backend implementation and new Motoko frontend/app code under the split structure, plus CI workflow path updates.

Thanks @Copilot. I checked each item against the original shared frontend. Every flagged file is byte-identical to the pre-split version — this PR only splits the example into self-contained Motoko/Rust copies (import paths, the PUBLIC_CANISTER_ID:backend env key, vite/bindgen wiring). None of these were introduced here, so to keep the split faithful and avoid re-testing behavior that already works, I'm leaving them untouched. They're better addressed upstream:

Pre-existing frontend items:

• store/vaults.ts — uninitialized vaultPollerHandle: harmless; clearInterval(undefined) is a no-op.
• store/draft.ts — draft restore checks content && tags: pre-existing; draft restore is effectively disabled.
• components/NewPassword.svelte / SharingEditor.svelte — Principal.fromText can throw outside the try/catch: pre-existing input-validation gap.
• components/EditPassword.svelte (move error handling): pre-existing; sets deleting instead of clearing updating.
• components/SharingEditor.svelte filter with .compareTo(): this is a real pre-existing bug — .compareTo() returns a string, which is always truthy, so the filter keeps all users. Worth fixing upstream.
• components/EditPassword.svelte class ternary: pre-existing and malformed, but a minor correction — it does not fail to compile. Svelte parses {'Read' in accessRights} as a complete interpolation and treats the trailing ? 'hidden' : ''} as literal text, so the class renders incorrectly rather than breaking the build.

Other:

• frontend/README.md (dfx / encrypted_maps_example / old env var): pre-existing and now stale relative to the icp-based setup; carried over unchanged.
• CI has no test.sh: intentional. None of these vetKeys examples shipped a test.sh on master, and CI's default identity is anonymous (2vxsx-fae), which several of these backends reject — a CLI test.sh would trap in CI even though it passes locally. The workflow is deploy-only, which still verifies build + install.

[marc0olo]

Follow-up: I removed frontend/README.md from both the Motoko and Rust copies (697d597). It was carried over from the original shared frontend and was the only frontend/README.md in the repo — no other example ships one — and it referenced dfx, an encrypted_maps_example canister, and the old CANISTER_ID_IC_VETKEYS_ENCRYPTED_MAPS_CANISTER env var, all contradicting the icp-based top-level README. Rather than maintain duplicate, misleading instructions, it's dropped.

On the CI point: the workflow already deploys both backends from their own working directories in separate jobs (motoko/vetkeys/password_manager and rust/vetkeys/password_manager), and both jobs pass. It stays deploy-only (build + install + asset sync) by design, consistent with the other vetKeys examples.
