fix(frontend): meet the 44x44 minimum tap target on every control (closes #43 )

Every interactive control measured below the 44x44 CSS px floor (Apple HIG, WCAG 2.2 SC 2.5.5) on touch viewports: .pin-btn at 16x16, the debug-log label at 89.3x14, #interval-select at 64x28 and, in the narrow layout, #pause-btn at 108.2x39.8. The pin button keeps its 16x16 layout footprint: the button box grows to 44x44 and matching negative margins take the growth back out of layout, so neither row height nor the icon's position changes in either layout. The select and the pause button get a min-height, the debug-log label becomes an inline-flex box 44 tall. Applied unconditionally rather than under a breakpoint, since a phone in landscape is above the 768px breakpoint and still a touch device.

 # Status

-pre-1.0. No git tags. `feat/reportbuf-storage` is merged; the backend, the CI
-workflow, and the backend repo standard files are all on `main`. Frontend and
-backend are both functional. Working toward the 1.0.0 milestone by closing the
-remaining repo-compliance issues on the tracker.
+pre-1.0. No git tags. Backend work in flight on feat/reportbuf-storage (dirty:
+src/main.js). Frontend is functional; backend is new and unmerged.

 # Next Step

-Confirm the `.gitea/workflows/check.yml` run is green (main always green
-policy). The workflow file is already on `main`; what is unverified is that its
-latest run passes.
+Land feat/reportbuf-storage: finish the in-progress src/main.js change, get make
+check green, and merge the branch to main. The branch adds the backend (buffered
+zstd-compressed report storage), the CI workflow, and backend repo standard
+files, so merging it also closes most compliance gaps.

 # Completed Steps

- 2026-08-10: adopted the org-standard `backend/.golangci.yml` verbatim and
-  moved the pinned golangci-lint from v2.7.2 to v2.12.2 (the `lint` stage of
-  `Dockerfile.backend` now pins the `golangci/golangci-lint:v2.12.2` image by
-  digest); the previous config declared `version: "2"` but used v1 schema keys,
-  so every threshold in it was inert and its green result was meaningless.
-  `backend/Makefile`'s `lint` target now asserts the config's sha256 against the
-  canonical file first, so drift from the org standard fails the build instead
-  of silently degrading to defaults
 - 2026-08-10: every interactive control now meets the 44x44 CSS px minimum tap
  target (`.pin-btn`, `#interval-select`, the debug-log label and, on narrow
  viewports, `#pause-btn`). The pin button's hit area grows via matching
  negative margins, so its layout footprint and row density are unchanged
- 2026-08-10: per-host status line wraps below the 768px breakpoint instead of
-  forcing horizontal page scroll at 320px
- 2026-08-09: `Dockerfile.backend` reworked to the mandated Go multistage
-  lint-stage pattern: separate `lint` stage on the hash-pinned
-  `golangci/golangci-lint` image, `COPY --from=lint` stage dependency,
-  `CGO_ENABLED=0` static build driven by `ARG VERSION`, and no more `COPY .git`
 - 2026-08-09: dotfile compliance — lifted `backend/.editorconfig` to the repo
  root so `root = true` covers the frontend too, and replaced `.gitignore` with
  the org model (OS, editor, node, and environment/secrets sections) plus this

 # Future Steps

+- Compliance top-up as one small commit: add .editorconfig and add the hooks
+  target to the Makefile
+- After merge, confirm .gitea/workflows/check.yml is on main and CI is green

 - Decide what to do with untracked resume.sh: commit it, gitignore it, or delete
  it
- Upstream fix needed in `sneak/prompts`: the org-standard `.golangci.yml`
-  enables `gomodguard`, which golangci-lint v2.12.2 reports as deprecated since
-  v2.12.0 and replaced by `gomodguard_v2`, so every backend lint run prints a
-  deprecation warning. The file is standardized and must never be edited in this
