fix(network): raise the remaining short limits for slow links (1.0.5, versionCode 7)

1.0.4 gave the metadata load 60 seconds. Every other call still had a
5 second call limit or OkHttp's 10 second defaults, so a slow warehouse
link could still fail start-up, enrollment or a process step.

All limits now come from one set, NetworkTimeouts:
- connect 10 s (unchanged value, now named)
- small calls 30 s: version discovery, branding, logo, reachability and
  the session heartbeat (were a 5 s call limit); device enrollment and
  status, sign-in, table and process-status calls (were a 10 s read)
- process init and step 60 s read and write, no call limit as before
- metadata load 60 s (unchanged)
- best-effort calls 5 s (unchanged): ending the device session and live
  screen frames, so sign-out, Change server and screen viewing never
  wait on a dead link

Not changed: the 3 s bounds around sign-out and the 30 s photo transfer
limit.

Tests assert the configured limits of every client (NetworkTimeoutsTest,
SlowLinkTimeoutsTest); the test that pinned the 10 s default now expects
an ordinary call to survive a 12 s answer.

 # Changelog
 
+## 1.0.5 (versionCode 7), candidate
+
+Not signed, tagged or published (prepared 2026-11-09). Updates 1.0.4 in place with the same permanent signer. Build and release steps: [RELEASING](docs/RELEASING.md#next-candidate-105-versioncode-7).
+
+- Slow links: the short network limits that 1.0.4 left in place are raised, and all limits now come from one shared set (`NetworkTimeouts`). Nothing else changes.
+  - Version discovery (`/qqq/v1/version`), branding, logo, the reachability check and the session heartbeat allowed 5 seconds for the whole call and now allow 30. A version check that took longer than 5 seconds stopped start-up with "Unable to check QQQ UI API compatibility".
+  - Device enrollment and status, sign-in, table and process-status calls waited OkHttp's default 10 seconds for the server and now wait 30.
+  - Process init and step wait 60 seconds. A client that gives up after the server has run a step invites the operator to run it twice.
+  - Opening the connection stays at 10 seconds, so a server that cannot be reached is still reported quickly.
+  - Unchanged on purpose: ending the device session (sign-out, Change server) and live screen frames keep a 5 second call limit; the 3 second bounds around sign-out and the 30 second photo transfer limit are not touched.
+
 ## 1.0.4 (versionCode 6)
 
+Published 2026-11-09 as prerelease [scanner-v1.0.4](https://git.kof22.com/QRun-IO/qqq-android/releases/tag/scanner-v1.0.4).
+
 - Loading the server's metadata no longer fails with "Error loading QInstance: timeout" on a handheld. The metadata response is about 1.7 MB and takes the server 4 to 8 seconds to build, and the default 10 second read timeout expired. That one call now allows 60 seconds; every other call keeps its short timeout. A timeout now reads "Timed out after 60.0s loading the server's metadata from <server>/qqq/v1/metaData".
 - Sign-out now also ends the identity-provider session in the browser when the server supports it (the same flow as "Sign out of company", now behind the single **Sign out** action), and every browser sign-in sends `max_age=0` next to `prompt=login`. Before, ordinary Sign out cleared only the QQQ session, so the provider session left in the browser silently signed the same person straight back in on the next sign-in. Servers without provider logout still get local plus QQQ sign-out. Stored-session restore after sign-out was checked and is not a cause (test added).
 - Includes 1.0.3 (versionCode 5): string widget icons and summary-only help content from current QQQ core are accepted. (PR 24)

The tag is on `main` `9bae976138c4447f3fa451ee49b8585e80f01847` (1.0.3 source plus Android PRs 26 and 27; a lightweight tag created with the release, like `scanner-v1.0.2`). Assets: `QQQ-Mobile-1.0.4.apk` (15015419 bytes, SHA-256 `F643872F4435B55F6A0B929D1762CAACB18010E5CC0B473C7B4BABBDC4299489`), `SHA256SUMS`, `INSTALL.md`, `RELEASE-NOTES.md`. The APK was downloaded back without sign-in and matched; `aapt2` shows versionCode 6 and versionName 1.0.4; `apksigner` verifies v2 and v3 with one signer whose certificate SHA-256 is `BDDB2D2F45A5925C643A83ABAF616C1EAB2387DC5CDA7B645A6F4C0D5B17A9FF`.
+- **Earlier releases:** `scanner-v1.0.2` (1.0.2, versionCode 4, signed candidate, prerelease) and `scanner-v1.0.0` (signed preview). 1.0.3 (versionCode 5) was signed and installed on the TC22 and MC9400 but never tagged or published; 1.0.4 includes it.
+- **Qualification of 1.0.4:** hosted CI on the tagged commit passed source checks, JVM unit tests, debug lint and the debug build; the emulator tests did not run because the runner had no usable `/dev/kvm`. No `lintRelease` result was recorded for the 1.0.4 build, and 1.0.4 had not been installed on a device when it was published.
+- **Next candidate:** **1.0.5 (versionCode 7)**, slow-link network limits; see [Next candidate](#next-candidate-105-versioncode-7). Not signed, tagged or published.
+- **CI note:** the shared workflow's Gradle step currently runs only the first line of `tasks` (unit tests, debug lint, debug build); the QA assembly line does not run. Run the release-variant lint and build locally before signing.
+
+## Next candidate: 1.0.5 (versionCode 7)
+
+Prepared on 2026-11-09 on branch `fix/slow-link-timeouts`. **Nothing is signed, tagged, installed or published for 1.0.5.** It updates 1.0.4 in place with the same signer and a higher `versionCode`.
+
+Change since 1.0.4 (details in [CHANGELOG](../CHANGELOG.md#105-versioncode-7-candidate)): the remaining short network limits are raised for slow links, from one shared set (`NetworkTimeouts`).
+
+Build from the exact merged `main` commit, with no `SCANNER_*` signing variables set:
+
+```
+./gradlew --no-daemon --console=plain :scanner-host:lintRelease :scanner-host:assembleRelease -PscannerVersionName=1.0.5 -PscannerVersionCode=7
+```
+
+Then sign `scanner-host/build/outputs/apk/release/scanner-host-release-unsigned.apk` in isolation, as for 1.0.4: `zipalign -P 16 -f 4`, then `apksigner sign` with the existing permanent key (certificate SHA-256 `BDDB2D2F...5B17A9FF`, recovered from the vault only for this step), then verify v2 and v3 with exactly one signer, `versionCode='7' versionName='1.0.5'`, and write `QQQ-Mobile-1.0.5.apk` and `SHA256SUMS`. Tag the built commit `scanner-v1.0.5`, create the Gitea release with the APK, `SHA256SUMS`, install notes and release notes, download the APK back and compare its SHA-256.
