Add Encrypted Sync page; cross-link from sync and backup pages
docs: migrate full user guide to the wiki as the single source of truth
Add the 9 remaining guide pages (Installation, First Dive, Dive Logging, Dive Sites, Equipment, Statistics, Import/Export, Dive Computers, Settings), rewrite Home as the getting-started landing page, and expand the sidebar. Screenshot placeholders stripped, guide/*.md links converted to wiki links, and broken features/* links removed. The guide is being removed from the app repo so the wiki is the sole copy to maintain.
docs: reconcile Multi-Device-Sync wording with the guide
- Align privacy line with the source guide (never sent to Submersion)
- Fix a second 'single shared log' misstatement: devices share one library, not one log
- Remove the Jurisdiction Endpoints section and its dangling cross-reference
docs: fix inaccurate sync model description in Multi-Device-Sync
The 'one library' tip described a single shared log that all devices read from and write to. That inverts the actual architecture: a per-device append-only changeset log merged via HLC last-writer-wins (each device is the sole writer of its own log and merges peers' logs locally). Reword to describe per-device copies that automatically merge into one converged library.

docs: reflect incremental sync in Multi-Device Sync
Submersion now stores a per-device changeset log (a small set of files) rather
than a single full snapshot, and syncs are incremental: after the first sync,
only changes are transferred, so large libraries stay fast and don't need the
app left open.
