Add read-only iCloud Photos support to the existing iclouddrive
backend via `service = photos` config option.
Also includes auth improvements on top of #9209's SRP authentication.
**Photos features:**
- 3-level hierarchy: libraries (Personal + Shared Photo Library) →
albums → photos/videos
- server-side smart albums (All Photos, Videos, Favorites,
Screenshots, Live, Bursts, Panoramas, Slo-mo, Time-lapse, Portrait,
Long Exposure, Animated, Hidden, Recently Deleted)
- User-created albums and nested album folders
- Live Photo `.MOV` companions as first-class entries
- Edited photo versions (`-edited` suffix) and RAW alternatives
- Duplicate filename dedup for camera counter wrap collisions
- Parallel cold listing for large albums
- Delta sync via CloudKit `changes/zone` - warm listings near-instant from disk cache
- Disk cache (libraries, albums, photos) with atomic writes for crash safety
- `ChangeNotify` support for FUSE mounts via `changes/zone` polling
- `ListR` support for `--fast-list` and recursive operations
- `--metadata` support - width, height, added-time, favorite, hidden
- Fresh download URLs per file - no stale URL failures on long copies
- FUSE mount documentation with recommended flags
**Auth improvements over #9209:**
- SMS 2FA fallback for users without trusted Apple devices
- Explicit push notification request - fixes iOS/macOS 26.4+ where 409
no longer auto-pushes
- Thread safety for concurrent FUSE callers (mutexes on session and client state)
- Session endpoint caching - skips ~5s `/validate` round-trip on warm start
- `Disconnect` support - clears auth state + disk cache
- PCS cookie support for Advanced Data Protection accounts, including
trusted-device approval for PCS cookies
Built on @coughlanio's Photos PoC (Closes#8734) and @mikegillan's SRP auth (#9209).

Replace AuthRequired bool with NoAuth bool on the rc.Call struct and
flip the auth check logic. Previously endpoints were unauthenticated
by default and had to opt in with AuthRequired: true, which led to
security vulnerabilities when developers forgot to set the flag.
Now all endpoints require authentication by default. Only explicitly
safe read-only endpoints are marked with NoAuth: true:
- rc/noop
- rc/error
- rc/list
- core/version
- core/stats
- core/group-list
- core/transferred
- core/du
- cache/stats
- vfs/list
- vfs/stats
- vfs/queue
- job/status
- job/list

Apple IDs are case-insensitive, but the SRP proof computation (M1)
hashes the username client-side. The old plaintext signin let the
server normalize the case, but with SRP the client must match.
Lowercase the Apple ID before use so mixed-case IDs authenticate
correctly.

This fixes China mainland iCloud authentication by deriving the Origin
and Referer headers from authEndpoint instead of hardcoding idmsa.apple.com.
Fixes compatibility with PR #8818 (China region support) and PR #9209
(SRP authentication).

Apple has deprecated the legacy /appleauth/auth/signin endpoint and
now blocks it, causing "Invalid Session Token" errors for all users
when their trust token expires. The browser login flow now requires
SRP (Secure Remote Password), a cryptographic handshake that never
transmits the password.
Replace Session.SignIn() with a multi-step SRP-6a flow:
1. authStart - initialize session at /authorize/signin
2. authFederate - submit account name to /federate
3. authSRPInit - exchange client public value for salt/B at /signin/init
4. authSRPComplete - send M1/M2 proofs to /signin/complete
The SRP implementation uses the RFC 5054 2048-bit group with SHA-256
and Apple's NoUserNameInX variant. Password derivation supports both
s2k and s2k_fo protocols via SHA-256 + PBKDF2.
The 2FA and trust token flow is unchanged. Auth headers for all
idmsa.apple.com requests now include X-Apple-Auth-Attributes,
X-Apple-Frame-Id, and use Origin/Referer of https://idmsa.apple.com.
Fixes#8587
This commit modernizes Go usage. This was done with:
go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...
Then files needed to be `go fmt`ed and a few comments needed to be
restored.
The modernizations include replacing
- if/else conditional assignment by a call to the built-in min or max functions added in go1.21
- sort.Slice(x, func(i, j int) bool) { return s[i] < s[j] } by a call to slices.Sort(s), added in go1.21
- interface{} by the 'any' type added in go1.18
- append([]T(nil), s...) by slices.Clone(s) or slices.Concat(s), added in go1.21
- loop around an m[k]=v map update by a call to one of the Collect, Copy, Clone, or Insert functions from the maps package, added in go1.21
- []byte(fmt.Sprintf...) by fmt.Appendf(nil, ...), added in go1.19
- append(s[:i], s[i+1]...) by slices.Delete(s, i, i+1), added in go1.21
- a 3-clause for i := 0; i < n; i++ {} loop by for i := range n {}, added in go1.22
