controller v0.121.0: backups page truth pass — remove dead Részletek card, real Tier-3 off-box state, SQLite-honest DB messaging

MinAgent: 0.81.0 (unchanged). Controller-only; no agent-API change, no backup-engine
behavior change. Fixes the self-contradicting /backups page (v0.120.0 live):

- Remove the dead "Részletek" card (redundant; kills never-set Tier2DriveGroups/
  ResticPassword fields + restic-pw element + toggleTier/toggleResticPw/copyResticPw JS).
- Per-app "3. mentés" row shows real off-box state via pure tier3State
  (unconfigured/off/escrow_pending/active) — "Hamarosan" placeholder gone.
- SQLite-honest DB messaging via pure dbSectionState (dumps/pending/embedded).
- Populate Tier1LastRun/Tier1LastStatus from ListRestorePoints; Tier-1/Tier-2 labels
  via timeAgoStr (relative), confirm() dialog keeps raw timestamp.
- Terminology split: "Távoli mentés (3. mentés)" (off-box, +#offbox-section anchor)
  vs "Távoli rendszermentés" (PBS whole-CT).
- Deploy page: add "Mentési beállítások →" link.

+9 internal/web tests (pure helper tables + buildAppBackupRows wiring + template
renders), 4 companion red-proofs run→fail→revert.

+> **2026-07-12 — v0.121.0: BACKUPS PAGE TRUTH PASS. MinAgent 0.81.0 unchanged. Controller-only, no
+> agent-API change.** Pure UI/data-plumbing on `/backups`; no backup-engine behavior change. Fixes the
+> self-contradicting live page: (1) **removed the dead "Részletek" card** (operator decision — redundant;
+> per-app rows + Adatbázisok section already carry the truth) — kills the last uses of the never-set
+> template fields `Tier2DriveGroups`/`ResticPassword`, the `restic-pw` element, and the `toggleTier`/
+> `toggleResticPw`/`copyResticPw` JS. (2) **per-app "3. mentés" row now shows real off-box state** via a
+> new pure `tier3State` (configured→toggle→escrow precedence): unconfigured/off/escrow_pending/active —
+> the "Hamarosan — B2/S3/SFTP" placeholder is gone. (3) **SQLite-honest DB messaging** via pure
+> `dbSectionState(discovered,dumps)` → dumps/pending/embedded (embedded-only box shows "–" + "beágyazott
+> DB-k a kötetmentésben", not a bare "0"). (4) **dead/raw fields fixed** — `Tier1LastRun`/`Tier1LastStatus`
+> now populated from `ListRestorePoints`; Tier-1/Tier-2 labels via `timeAgoStr` (relative), confirm()
+> dialog keeps raw. (5) **terminology split** — off-box section = "Távoli mentés (3. mentés)" (+
+> `#offbox-section` anchor); whole-guest PBS card = "Távoli rendszermentés" (was both "Távoli mentés").
+> (6) deploy page gains a "Mentési beállítások →" link. DECISIONS: Részletek removed as redundant
+> (operator-approved); "Távoli mentés (3. mentés)" (app off-box) vs "Távoli rendszermentés" (PBS whole-CT)
+> are two distinct customer-facing names. Pure helpers in `internal/web/backup_page_state.go`. +9 web
+> tests, 4 red-proofs. Observations: orphaned style.css classes from the Részletek removal left in place
+> (details-tier*, repo-encryption*, restic-pw-field, drive-detail-*, tier-empty-state, repo-info-row*,
+> repo-tier-title) — noted, not cleaned. Backlog: felhom.eu backup-architecture.md offbox refresh (separate task).
