docs(wiki): catch the manual up to 1.29.0 and add the three run modes it never had

The wiki was written for seven run modes and never received Grok Build, DeepSeek
Harness or OMP. They now appear everywhere the others do: the modes table and
per-CLI notes, install commands, environment prefixes, the Quick Start table, the
requirements rows, the vocabulary, and every "seven modes" count.

The 1.27 to 1.29.0 changes land on the pages that own them: attaching a case to an
existing container, multi-case adoption and the copy-a-case picker (Docker Cases);
file reads over ssh in remote cases and what stays unavailable (Remote SSH Sessions,
Working With Files, Security); single-page app routing, frame recovery, localhost
links as tabs and the egress guard (Web Tabs); DeepSeek as the one non-Claude mode
with real stop/blocked signals and Approvals items, Codex's own work detection,
last-response, the model-endpoint routes and refreshed counts (HTTP API, Driving
From An Agent, Hooks, Notifications, Keeping Agents Running, Core Concepts);
Shift+drag, right-click copy, Auto Copy, the Ctrl+Z guard, font weight, the vertical
rail and its activity sort (Keyboard Shortcuts, Input And Voice, The Dashboard,
Settings Reference); the 600px phone cutoff, Codex shift arrows and iPhone Duo
(Mobile Guide); the Docker Compose route and its update rule (Installation, Running
As A Service); four new symptom entries and a "which CLIs" question (Troubleshooting,
FAQ).

Custom model endpoints are deliberately left to #430, which adds that page and edits
Agent CLIs, Settings Reference and the sidebar; these edits stay out of the regions
#430, #428 and #376 touch, and all three still merge cleanly on top.

Both READMEs: the web-tab menu entry is labelled "Add URL" in the UI, not
"Add dashboard".
