Complete Japanese translation and enable the JA documentation build

[sanak]

Summary

Completes the Japanese localization of the workshop and turns the Japanese
build on.

• Translates all 26 Japanese catalogs under locale/ja/LC_MESSAGES/ to 100%
  coverage (no untranslated or fuzzy entries remain; verified with
  msgfmt --statistics).
• Adds "JA" to WORKSHOP_LANGUAGES_TRANSLATED in CMakeLists.txt.

Why the CMakeLists.txt change is needed

ja was already listed in WORKSHOP_LANGUAGES, but not in
WORKSHOP_LANGUAGES_TRANSLATED, so make doc never produced Japanese output.
With the catalogs now complete, the language can be built and published like
es and sv.

Notes for reviewers

The diff is larger than the amount of new text. The ja catalogs were
regenerated from the current POT before translating, which re-wraps existing
lines and refreshes the PO headers. Roughly 790 of the deleted lines are this
re-wrapping rather than removed content.

Some msgids on develop were stale. The Weblate-managed ja catalogs were
still based on POT-Creation-Date: 2024-12-16 and had drifted from the current
sources — for example docs/general-intro/overview.rst:36 reads
There is no need for pre-calculation. while the ja catalog still carried
precalculation. This PR brings the msgids back in line with docs/*.rst.

Weblate coordination. Because these files are managed by Weblate, it is
probably worth locking the Japanese component (or letting Weblate rebase) around
merging this, so the re-wrapping does not fight with in-flight Weblate commits.

Terminology and Japanese/Latin spacing were kept consistent across all chapters.

History

Rebased onto the current develop. Original authoring dates are preserved. Two
temporary CI commits used for previewing the Japanese build were dropped and are
not part of this PR.

Walkthrough

Japanese is enabled by default in CMake. Japanese gettext catalogs were added or updated for the workshop introduction, core chapters, appendices, examples, and UN Sustainable Development Goals chapters.

Changes

Translate workshop chapters locale/ja/LC_MESSAGES/advanced/*, locale/ja/LC_MESSAGES/basic/*, locale/ja/LC_MESSAGES/interactions/*	Japanese catalogs cover topology, routing, SQL functions, point routing, QGIS, GeoServer, and OpenLayers instructions.
Translate appendices and examples locale/ja/LC_MESSAGES/appendix/*, locale/ja/LC_MESSAGES/examples/*	Japanese catalogs cover installation guidance, video tutorials, and routing examples.
Translate UN SDG chapters locale/ja/LC_MESSAGES/un_sdg/*	Japanese catalogs cover SDG introduction, data preparation, health, energy, and sustainable cities chapters.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk:🟠 High · up to 1a0dd

The PR would publish Japanese documentation containing unqualified PostgreSQL trust authentication guidance that can permit unauthenticated role assumption, while several catalogs still have fuzzy headers and examples contain incorrect executable or function identifiers. The JA build should not be enabled until these issues are corrected, catalogs regenerated, and gettext validation passes.

Poem

A rabbit hops through translated text,
With Japanese pages freshly dressed.
Topology, routes, and SDGs align,
Each catalog now speaks in a new design.
“JA is ready!” the bunny sings,
While CMake gives it wings.

Finalize the Japanese PO headers before enabling the build. The affected catalogs retain header-level #, fuzzy flags and/or stale template metadata. Remove the fuzzy flags, regenerate headers from the matching current POT files, populate final metadata, and rerun msgfmt --check --statistics so the catalogs meet the claimed 100% coverage.

🌐 Web query:

PostgreSQL current documentation pg_hba.conf trust authentication anyone who can connect log in as any database user without a password

💡 Result:

In PostgreSQL, the "trust" authentication method in the pg_hba.conf file allows a connection unconditionally [1][2]. When this method is used, PostgreSQL assumes that any user who successfully connects to the server is authorized to log in as any database user they specify, including superuser roles, without needing a password or any other form of authentication [3][1]. While the "trust" method is technically accurate as described, it is critical to understand the associated security implications: 1. Scope: This method only skips the password/authentication step for connections that match the criteria defined in the pg_hba.conf file (such as specific IP addresses or local sockets) [3][1]. The database still enforces other restrictions defined in the pg_hba.conf file, such as the allowed database and user columns [3]. 2. Security Risk: Using "trust" is generally considered insecure for any environment where unauthorized users might access the network or the system [3][4]. It is primarily intended for use on single-user workstations where the operating system's security is sufficient to protect the connection [3]. 3. Recommended Usage: It is seldom appropriate to use "trust" for TCP/IP connections, including local loopback connections (127.0.0.1), in a multiuser environment [3]. For local connections, alternatives like "peer" authentication are generally recommended [5]. If "trust" must be used on a multiuser machine (often as a temporary measure during initial setup), it should be protected by strict file-system permissions on the Unix-domain socket [3][4]. Because PostgreSQL processes pg_hba.conf records sequentially, a "trust" entry appearing early in the file will take precedence over subsequent, more secure authentication methods [1]. Therefore, it is standard practice to use specific, secure authentication methods for network connections and reserve "trust" only for highly restricted, local scenarios [3][1].

Do not publish trust as an unqualified fix.

The source configures trust for all local-socket and loopback connections. This allows unauthenticated users to assume any database role. Restrict this guidance to an isolated workshop VM, or replace it with password-based authentication in docs/appendix/appendix-2.rst and regenerate the catalogs.
