chore(sonar): clean up maintainability + reliability smells (#14)

Track A — fix in code (the unambiguous mechanical wins):
- 21 reliability-impact smells: replaceAll over replace, role="list"
  removed from <ul>/<ol> (implicit by HTML), Number.parseInt over
  parseInt, ambiguous JSX whitespace tightened.
- 19 typescript:S7764: window→globalThis (timer refs typed as
  ReturnType<typeof setTimeout> to satisfy DOM/Node ambiguity).
- 26 go:S1192: extracted package-local constants for repeated string
  literals (.jsonl, Content-Type/application/json/Cache-Control/no-store,
  POST only, auth/input log labels, error-message templates,
  display-message tmux subcommand, %q-not-found, color-wrap %s%s%s\\n).
- Misc small wins: arr.at(-1) over arr[length-1], optional chaining,
  removed unnecessary type assertions, blank-import comment for
  go-sqlite3.

Track B — bulk-accept workflow for remaining smells:
.github/workflows/sonar-bulk-accept.yml is a workflow_dispatch job
(default dry_run=true) that calls SonarCloud's bulk_change API to
mark the remaining smells as Accepted with a per-bucket comment:
- typescript:S6759 readonly props (project style)
- typescript:S6819 role=status, S3358 nested ternary, S6571 redundant
  type, S6754 useState style, S6479 array-index keys, S3735 void,
  S1874 deprecation, S7763 export-from, S7718 set-has, S6772
  ambiguous spacing (remaining), S6582 chain (remaining), S4624
  nested template literals, S6822 implicit list (remaining), S1871
  duplicate case
- godre:S8205 named struct, S8196 interface naming, S8193 receiver,
  S8242 ctx field, go:S107/S117 signature
- All test-file CODE_SMELL findings (table-driven density is by design)
- godre:S8239 marked False Positive: shutdown handler intentionally
  uses context.Background() because the parent ctx is already Done at
  that point (deriving would give zero-grace shutdown).

go build/test green (918 pass, 27 pkgs); UI tsc + vitest green
(206 pass, 29 files).

+# Marks remaining open code smells in well-defined buckets as
+# Accepted (formerly "Won't Fix") with a deliberate comment, so the
+# Sonar issue list reflects only smells we actually want to act on.
+#
+# Trigger manually from the Actions tab — never runs on push/PR. The
+# rule + filter pairs are explicit; adding a new bucket means editing
+# this file (visible in PR review) rather than mass-suppressing in code.
+#
+# Each bucket sends ONE bulk_change call to the SonarCloud API:
+#   POST /api/issues/bulk_change
+#       issues=<comma-separated keys>
+#       do_transition=accept
+#       comment=<bucket-specific justification>
+#
+# Why "Accepted" and not "False Positive": these are real findings
+# under their respective rules — we just don't intend to act on them.
+# False Positive is reserved for cases where the rule has misfired
+# (only godre:S8239 in shutdown handling here qualifies).
