fix: add MIME types for OpenDocument formats

[phil-davis]

Add MIME type mappings for additional OpenDocument formats for file types odc, odi, odm, otc, and otg.

Add MIME type aliases for chart and image formats that were currently missing in the default mimetypealiases.dist.json file.

Update mimetypelist.js using ./occ maintenance:mimetype:update-js

Fixes #36467

[phil-davis]

IMO this is an easy "fix", to add these MIME types.
I don't know if there is any relevant test to modify/add.

Overview

This PR adds MIME-type mappings for the OpenDocument file extensions that were previously unmapped (served as application/octet-stream), plus matching icon aliases. It directly resolves #36467 ("Some MIME types missing for OpenDocument formats"). An earlier automated analysis of that issue identified six missing extensions — odc, otc, odi, oti, odm, oth — and all six are covered here. The PR also goes further and adds otg, otp, ots, ott, which were missing too. Nice.

Correctness (MIME strings)

All MIME strings are the official OASIS OpenDocument types and match exactly:

• odc → application/vnd.oasis.opendocument.chart ✓
• otc → application/vnd.oasis.opendocument.chart-template ✓
• odi → application/vnd.oasis.opendocument.image ✓
• oti → application/vnd.oasis.opendocument.image-template ✓
• odm → application/vnd.oasis.opendocument.text-master ✓
• oth → application/vnd.oasis.opendocument.text-web ✓
• otg/otp/ots/ott → graphics/presentation/spreadsheet/text -template ✓

No typos, no accidental removals. Both mimetypemapping.dist.json and mimetypealiases.dist.json remain valid JSON (205 and 88 keys respectively). The new mapping keys are inserted in correct alphabetical position (odc before odf; otc/otg/oth/oti/otp/ots/ott correctly ordered around otf).

Completeness (icons / aliases / changelog)

• Aliases: the new chart/image entries map to x-office/drawing. Reasonable (chart/image have no dedicated icon). They are placed in the existing text-web→graphics-flat-xml block, which is fine — the OD section of this file is grouped by icon target rather than strictly alphabetical, so the placement matches the existing convention.
• JS-side icon list (optional): core/js/mimetypelist.js carries its own copy of these OD→icon mappings and currently also lacks the chart/image entries. This PR does not touch it. The .dist.json aliases are the authoritative source, so functionality is correct, but if you want the bundled JS hint list consistent you may consider mirroring the four chart/image aliases into mimetypelist.js. Optional — not blocking.
• Changelog: present (changelog/unreleased/41648) — good. Minor nit: the body lists "odc, odi, odm, otc, and otg" and omits oth/oti/otp/ots/ott that the PR also adds. Cosmetic only.

Verdict

Approve with minor nits. The PR correctly and completely fixes #36467 — all six extensions flagged by the prior automated analysis are mapped with the right OASIS MIME types, JSON is valid, ordering is consistent, and a changelog entry is included. The only suggestions are optional (mirror chart/image aliases into mimetypelist.js, and tidy the changelog wording). Thanks @phil-davis.

Re-reviewed after the HEAD commit changed since the last sweep (prior verdict: approve-with-nits). The new push is a meaningfully expanded and improved version of the change.

What changed since the last review

• Mapping now covers the full OpenDocument template/format set: odc, odi, odm, otc, otg, oth, oti, otp, ots, ott (previously a narrower set).
• The two prior optional nits are both resolved:
  • mimetypelist.js icons now mirrored — regenerated via occ maintenance:mimetype:update-js; chart/image OpenDocument types now have icon entries (x-office/drawing), consistent with the existing graphics entries.
  • changelog present and well-formed (Bugfix: header + body + PR link), matching repo convention.
• Chart/image aliases added to mimetypealiases.dist.json.

Verification performed

• All 10 MIME strings are the correct official OASIS OpenDocument media types — no typos (...chart, ...chart-template, ...image, ...image-template, ...text-master, ...text-web, ...graphics-template, ...presentation-template, ...spreadsheet-template, ...text-template).
• Both *.dist.json files validated as syntactically valid JSON on the PR branch.
• No accidental removals — the change is purely additive. The single "deletion" in the diff stat is just the regenerator alphabetizing the JS alias array (x-office-drawing before x-office-presentation).
• Ordering: mapping additions are alphabetically placed within their clusters; alias additions follow the file's existing (loose, grouped — not strict-alpha) convention as already present on master. Consistent with repo conventions.
• The unrelated application/toml and application/x-openvpn-profile entries that appear in the JS diff are pre-existing mappings on master that the regeneration tool correctly surfaced into the JS — not new behavior introduced by this PR.
• No regression risk: surfacing existing data + additive MIME mappings.

Clean, complete, and well-formed. No requested changes, no caveats.

Verdict: approve.
